are definitely wrenches. Even I know that.
So tools aren't my thing but I do like robots and I use a lot of these combination wrenches in my assemblage work. Of course, I don't call them "combination wrenches." I call them "doohickies with a claw end and a circle end." I don't know why you would buy this fabric. Maybe you like cars. Or tools. Or robots. If you like robots, check out my "I Heart Bots" collection, which is chock full of robot designs. This design coordinates with my Robot Cheater Quilt: https://www.spoonflower.com/collections/340924-robot-cheater-quilt-by-trilby_works.
