It's persimmon season...


Fuyu Persimmons, 8" x 10"Prismacolor colored pencil on Stonehenge paper


Persimmons are starting to appear at the market! These tomato-shaped Fuyu persimmons are available now, which means the bigger, cone-shaped Hachiyas will be here soon. I found the leaves, or sepals, quite interesting because they appear in arrangements of four, which seems a bit unusual in the fruit world. I've written before about the star shapes and multiples of five that are found in so many fruits and vegetables, but these are definitely a symmetrical, cross-shaped arrangement of four. 

When I draw shiny fruits and vegetables, it's easy for me to overwork the burnishing, so I deliberately held back a bit on these. I wanted to capture some of the frosty "bloom" that appears on the skins, which was quite a challenge; it'd have been easier to have polished them up before I drew them!



Here are some WIP shots; I hope to have some Hachiya persimmons as models before too long!

Horned Melon

Horned Melon, Cucumis metuliferus
Prismacolor colored pencils on Stonehenge paper

Have you seen these little spiky creatures at your grocery store? I saw some a few months ago, but didn't buy one as I had no time to draw it then. I've been scouting the produce section for them ever since, and—lo and behold—there they were last weekend! (I was going to get two, but that was before I realized they were about $6 apiece. Yikes.)

The horned melon is also known as the kiwano melon or the African horned melon, but I prefer its cute nicknames: hedged melon, blowfish melon, and jelly melon.


I drew the outside first and tried to see if the spikes fell in any kind of pattern or symmetry. (You know about my obsession with radial symmetry in nature.) But they seemed to be rather randomly arranged. So imagine my surprise when I cut it in half to draw the inside: My cut went through 3 spikes that were in an almost perfect equilateral triangle! In fact, the whole cross-section was shaped like a circle with 6 flattened faces. The cross-section looks very much like a cucumber (which is in the same family).


I am intrigued by fruits and vegetables, such as watermelon and kiwi, whose insides are in sharp contrast to their outerwear. This one pretty much wins the prize in that category, doesn't it?
(And, no I haven't tasted it...yet!)

Happy 27th birthday to my son, who brought me this sea urchin shell—packed in his backpack—all the way home from his recent trip to New Zealand! He knows that I have a fascination with drawing examples of radial symmetry in nature (often based upon multiples of 5), which I've previously posted about here.

Before I sat down to draw this "test" (which, I learned, is the proper terminology for a sea urchin shell), I was curious whether or not it was as perfectly round as it appeared to my eye. So, I printed out a little template of a circle the same diameter as the shell. I laid the shell over it on my lightbox, and...wow! Mother Nature never ceases to amaze.




Since the shell is composed of a beautiful almost monochromatic blue-grey-green palette, I ended up using a toned Strathmore charcoal paper (the smooth side) and only graphite and 2 Prismacolor pencils: Jade Green, and White Verithin. (Sorry for the uneven lighting; I was too lazy to scan, so I just shot this at my desk with my iPhone.)


As I examined the shell closely, I was curious about the texture of the surface, and did a little research—they're fascinating creatures! The raised bumps are where the spines had been attached with an ingenious ball-and-socket mechanism, and all of the tiny holes are where the soft tube feet once extended. What an amazing little structure!

Pumpkins in December?

Prismacolor colored pencils on Strathmore Bristol, Vellum

It has been far too long since I posted a new drawing, but rest assured that all is well. I've just been working on some "Do-not-open-before-Christmas" holiday projects that couldn't be posted, or surprises would have spoiled. Now that the holiday crush is behind us, I'm re-charged (I'm hoping it's not just a sugar high) and resolved to get back to more regular drawing —and posting!

This pumpkin drawing was commissioned by a lovely woman, the aunt of one of my close friends. My friend had recently given her a framed print of my artichoke cross-section drawing, chosen because her aunt lives in Half Moon Bay, a coastal town north of here (and south of San Francisco). Half Moon Bay, besides being famous for its pumpkins (it hosts a huge Pumpkin Festival each October) is also known for growing artichokes and other vegetables. I'm tickled that she asked for a pumpkin drawing as well as one of Brussels sprouts on their stalk. (The latter has a short season, and since I almost always draw from real "models", I'd better get that one done soon!)

In case you're wondering, I chose to draw this "bird's-eye-view" since it is a companion piece to this one:



Here are a couple of work-in-progress shots:


I hope that you are enjoying some relaxing post-holiday time as well. Next up for me...blog visits! (And maybe one last slice of cranberry bread...)

And one last important note: Thank you for all of the supportive comments, emails, and good ol' positive thoughts that you sent my way after my recent post about Parkinson's Disease. Your kind words mean more than you know.

Turban Squash

Turban Squash
Prismacolor colored pencils on Strathmore Bristol, vellum finish

"I wonder how they do that?!" exclaimed an older woman in the grocery line as she pointed to my turban squash.

Isn't nature amazing? Of all of the winter squash and pumpkins that I adore, this one has got to be the most exotic. There were lots of them at the farmer's market this weekend, and when you view them right-side-up, they do look like little heads sporting turbans.

This squash was the perfect little model: no wilting like a flower does, no drying out like blueberries and tomatoes do. It just sat there in all of its I-can-last-all-winter smugness. I guess that's why I like drawing botanicals like nuts, pine cones and winter squash—there's no hurry. So, I took my time (and used almost every pencil that I own in the green and orange families) and even made work-in-progress scans. As is often the case, I wasn't really happy with this final scan...the reds look a little splotchy and bright. So I took a quick shot with my iPhone4:
Not bad, huh? I stopped short when it came to adding a shadow, as I kind of like how it looks without it. What do you think? Does it look unfinished without one?

Here are the WIP views (click to enlarge)

Illustration Friday: Mesmerizing

I'm beginning to think that I have the Kenner toy company to thank for my fascination with radial symmetry. In 1966, they introduced the Spirograph, one of the most mesmerizing toys of all time. I drew with mine until its skinny pens dried out and I had to make do with whatever else we had in the house. And when they introduced the Super Spirograph a year later, well, I was one obsessed little geek...er, little girl.


I'm sure the seeds of my interest had already been sown: Like most kids, I loved making paper snowflakes, and I still love the expressions on kids' faces when they open up that pie-shaped paper they've been cutting. But if I had to guess, my very first glimpse of the amazing radial symmetry found in nature was probably this one—still one of the most elegant examples, to be sure—the star in the center of an apple.

So, thank you, Kenner Products, for the fact that I once wrote a college term paper on these, have this on my coffee table, and these in my portfolio:

If you're interested, here's a link to a fabulous page by someone who clearly loved his Spirograph as much as I loved mine. Did you have a favorite creative toy growing up? Let the nostalgia begin!

Carnival Squash, Three Ways

Prismacolor colored pencils on Strathmore Bristol Vellum

This week's topic on Illustration Friday is "Disguise", which brought to mind this drawing of a Carnival squash that I did last fall.  While I was drawing the colorful, mottled skin, I kept thinking that it looked like a camouflage pattern. I'm sure that Mother Nature had some purpose in mind when creating this botanical disguise.

This was the first of what was going to be a series: 3 views (top, side, bottom) of the same fruit or vegetable.  As I've mentioned before, I'm fascinated by the patterns and shapes found in nature. Maybe it's my background in drawing architectural plans and views, but I enjoy comparing the "plan view", and the "side elevation", etc.  I love that the cross-section of the stem of this squash (like many fruits and vegetables) is a 5-pointed star shape, and the number of sections in pumpkins or squash is almost always a multiple of five. 

Now that I've revisited this piece, I'm all jazzed to get going on the series again.  And even more so since fall is almost here: pumpkins, gourds and winter squashes—with their rich colors and their lumpy, bumpy shapes—are some of my favorite things to draw!

Note to Blogger users: Are you having issues with your blog not updating on your followers' blogrolls?  This has happened before, and then it randomly starts working again later. Is this happening to any of you? Do you know of a fix?

Illustration Friday: Launch


An alien spacecraft preparing to launch?

Nope, it's a passion flower, easily the most exotic plant in my yard, and certainly one of my favorites. And "launch" it does, believe me—I'm constantly hacking back the vines and ripping out new shoots that spring up all over my garden. I have two slightly different varieties in my yard, and both grow like weeds. Better than weeds. It's indestructible. You can't kill it. Hmmm, maybe it is an alien life form after all...

As one might expect from a bloom this intriguing, the passion flower, or passiflora, has quite a bit of lore and legend attached to it. Its name comes from the Passion of Christ, as Spanish missionaries saw all kinds of symbolism in it, which you can read about here . In cultures where Catholicism isn't as widespread, it is sometimes called the clock flower (although there are 10 not 12 petals) or the Maypop—its hollow fruit pops open when you squeeze it.

While fascinating to look at, it's a bit of a challenge to draw. The flower doesn't last long, and closes when the light fades. I intend to try this one again, and hope to show the beautiful vines and leaves, the different stages of the bloom, and the fruit. In the meantime, check out some of these amazing photos...rather bizarre, but so beautiful!

Illustration Friday: Journey


This week's Illustration Friday word is "journey", so I give you...a shrub. 

This is Brunfelsia pauciflora, but I prefer its evocative common name,  
Yesterday-Today-and-Tomorrow.

Walking through our neighborhood, a friend and I used to pass one of these gorgeous plants, and we'd always comment on how much we liked it.  Once I finally learned its name, I liked it even more.  The name is derived from the fact that the blossoms start out a bright violet, fade to a beautiful lavender about a day later, and end up almost white.  Its poetic name makes it a perfect gift to celebrate a birthday, a new baby, any landmark along life's journey.
  "Learn from yesterday, live for today, hope for tomorrow."
—Albert Einstein

Note: For some reason, my jpg images are looking fuzzy once they're placed into this post. (Click on the drawing if you'd like to see how it should look.)  If anyone has advice for me, I'd love to hear from you!
