I've gone back to Prismacolors for this. Before I bought my new electric pencil sharpener (Bostitch SuperPro 6), I had all but given up on these. They were breaking like crazy (in my old duller sharpener), and I thought I might never use them again. But now that I have the new sharpener, which only rarely eats one, they're back on my list of usable pencils. And I'd forgotten how much I love them.
I laid out three of the best chilis in the package, and am trying to work 'left to right' as best I can, to avoid smearing the parts I've already done (I'm right handed - if you're left handed, you would work the opposite direction). I don't always do this, but sometimes it works out to be the best way.
I started with a Raspberry pencil, and kind of mapped out the wrinkle patterns in each chili. Now I'm going back in to each one and rendering it out. The last chili is very very dark, almost black. I've been avoiding using actual black to get the darks dark enough, but I may have to break down and use it. So far I've stuck to Black Grape and Black Cherry to do the darkest darks. I'll wait until I have them all to the same point of finish, then do the final tweaking at the end.
I tend to stick with one brand of pencil when I start working on a piece - I'm not sure why. Maybe I'm just lazy! I could try some Polychromo Indigo I think, or something else to do the darkest darks. I'll figure it out when I get there!
