I am not really fussy about my brushes when I am using a lot of mixed media products, such as gesso, modge podge and modeling paste. In fact, I have allowed on of my favorite palette knifes to stay grungy because I like the textures added when applying heavy body acrylics in layers to a canvas.
However, I am really fussy about the scissors that I use to fussy cut. I use two fiskers products. A pair of teflon coated scissors and a smaller pair of spring-loaded scissors.
Tonight I gathered several figures that I plan to use on multiple canvases to fussy cut out of plain 65 lbs. weight cardstock. This gives me a smooth surface to apply papers and paints to complete the figures.
Now when I am done, I can set aside in the studio to keep moving through the creative process rather than having to stop and laboriously cut the fine details before I can move on.
