Your sketch cards are very colorful. What media do you use? Do you get pre-cut cards, or do you hand-cut yours, like I've been doing?
Prismacolors are great (my colored pencil set is still in that "too awesome to use" category, though. Pricey!), I've tried a few of them. How well do they blend? Does the ink last a good long time? And after layering on some color, does the paper start getting this gritty feeling to it?
I like them, they blend very well, but it depends on the paper stock, they bleed through some thinner paperstock, but there is hardly any gritty feeling.
Something that started with a doodle, turned into a full art piece on a small notebook cover, and loader page.

I would take it easy with the white gel pen. It's a very fun and useful tool, but it can quickly become a little too much. I try to use it only on surfaces that are specifically supposed to be highly reflective. In other cases (on matte surfaces), I'll use it to break a solid line (an inked line) to soften it. But lately, I've tried to use it very sparingly. Just a thought!
Thanks. It's actually the first time that I'm trying to use them in my art. Working on a large-format hand-drawn/digital Super Mario Bros - Star Wars crossover poster now in colored pencils, inks and maybe prismacolors.
