My campaign buttons tops measure 2 and 1/4 inches across. I cut my fabric circle big enough to go around the button and finish as a yo yo on the inside (edges turned in) with 2 layers of batt just over and inside a bit. I also hand stitched my zipper straight up instead of gathering as in the Craftpassion instructions because I wanted enough room for my thimble. I left a little space in the bottom yo yo for a magnet to be hot glued in to make it a magnetic holder for my needles. She finished the insides of hers but I didn't find it necessary by doing the yo yos and I don't mind the zipper ends not being under the covers like hers. I will try to attach a pic of the inside.
