I used a fabric covered button on this one. I think I like the plain yellow button more.
I made this out of 4 inch squares of fabric left over from a seamstress who made wedding dresses. I went to their garage sale and the seamstress had long since passed and the daughter who was about 70+ was selling off things. I picked up a whole box of ends of pretty wedding dress material! I don't recall what I paid but it must have been very little.
