I will say this for SOC so far - the colors have been BRIGHT! This week it's lime green and purple. I seem to mostly be making backgrounds for these challenges, and will use them up in various things eventually.
I started out with a lime green painted background, then scraped some heavy gel medium mixed with purple paint thru a stencil but it bled and oozed. :-( Ugh. But I'll use it for a postcard with something over the smeared areas.
Unhappy with the oozing, I painted a piece of watercolor paper with purple paint, let it dry, then scraped modeling paste mixed with line green paint thru a stencil. Very cool textured background and no bleeding. The thicker modeling paste is the trick.
You can see that there is a bit of color difference between the green squares on the upper 2/3s of the card and the bottom third. The top was done with Liquitex modeling paste, the bottom with Liquitex coarse texture gel. They both have a lot of texture but obviously absorb the paint differently.
I also scraped a bit of leftover green modeling paste onto the lime card and pressed a stencil into it. That has possibilities.
Great colors, ones I don't use much, at least the purple, but I like them and will use them again. Maybe gelli prints this afternoon??
