I'm working on whipping up a batch of fabric covered robot buttons. I love making these. I have a hoarder-level collection of fabrics that I can use, but I usually just make robots. I wish I had bought more of this fabric. It's a special Japanese import that I picked up in Minneapolis. I love the personalities of all the robots. I also like how by shifting the robot around on the button, it changes the whole "mood" of the button.
I put the tie-tack pins on the back. Not only are they easier to attach to the button, I think it makes them easier to wear than other 1 inch buttons.
