I found these big 2.5" Tree House Studio lapel button forms at Hobby Lobby during a trip back to the States. You can use them for all sorts of occasions. They're fun and super easy to put together. I use a die to cut out my circle image, place it right side up in the front part, then snap in the back—easy peasy.
I worked up my design on the computer with a digital image and Fluffy Slacks BTN font. This is a birthday gift for a friend.
