Carving rubber stamps is my favorite printing technique. For years, I used grey rubber, but when Lisa Chin introduced me to Inovart Eco Carve, I changed loyalties. I did so because, Eco Carve is firmer than the grey stuff, though it carves like butter. The firmness allows for finer lines.

I continue to swatch and print a new color triangle and am happy to say I am past the half way point. I have 15 colors swatched in gradations of four each. This means I have 13 more colors to go. Woot!
Soon, I will have 4 color triangles to choose colors from! I am a greedy little dragon! I want even more triangles! 
With each color grouping I swatch, I am using a new multicolor print set. When I am finished with this new color triangle, I will have, So. Much. Fabric!! And there is nothing wrong with that.
