in the hardware store. I needed to go somewhere to get a few foam brushes, so instead of cheap, I went to the closest place, a small hardware store not too far from my house. As I cruised around, I stumbled upon the plumbing section and struck it rich.
There were all sorts of texture making things. . . the original use of these items escapes me. I'm sure the checkout lady wondered what I was going to do with the assortment of PVC things, none of which fit together in any manner, in addition to some ridged shelf liner and some diamond shaped plastic gutter coverings. It's so easy to find round things to make shapes and textures, but I found some square things and some round things with grids or lines in the openings. I can't wait to experiment with these plumbing supplies.
