I have been playing around some more with buttons and I guess what I am doing is basically decoupage. In refining my method, I have decided that I prefer to sew the button in place first. Then I use masking tape to attach pieces of aluminum foil under and around the button to protect the fabric. The two I have been working on are for Carolyn's Pansy RR blocks.
This first one was done on a green button to match the colours of the block. Since I don't have my printer out here this summer I have been limited to what images I have been able to find in some of my expendible books. So, I found a pansy and fussy cut it out. A layer of of the Fimo glaze went on the button and then the pansy went on top of that. I added a couple more layers of glaze and then decided that I would like to add some glitter. Then another layer of glaze went on top of that. I think I like how this one turned out.
This is the second one I am working on for the other block. I used a nice mother of pearl button from my stash and sewed it on backwards since the back was flatter. Another fussy cut pansy was applied in the same way with the glaze. This photo shows it with just one coat of glaze on top. I will likely add a couple more before I am done but this time no glitter I think.
