I cut the wrapper at 2"
To make the bottom I welded a 2" circle and two 3" capital I's (from Artiste but any skinny rectangle shape would work). I rotated one of the I's so they formed a plus shape then placed the circle in the middle. (This gives the circle four 1/2" tabs.)
I folded the tabs and used liquid glass to glue them on the inside of the wrapper. The handle (just a 3/4" strip) was also attached with liquid glass. I kept it simple with some buttons, but it could be dressed up so much more!
