I used my free motion quilting practice sandwich to make a cover for my quilt picture book. (I take  pictures of all my quilts and put them in this book and write a little story about each one.)
I'm trying to improve my free motion quilting so I have a lot of practice sandwiches. And what can you do with them??? Make some purses or a book cover. This sandwich I used was dyed with rust.  The instructions for a book cover you can find on http://www.academyofquilting.com/ There is a free class on Book Cover and it is decorated beautifully.

This is the front, the button is made from coconut.

This is the back. As you can see I need much more practice on free motion feathers.
