I used some paper piecing scraps to decorate Altoid-like tins for Christmas presents.
I used a layer Mod Podge to glue the fabric to the tins and then applied a few more layers of Mod Podge, similar to decoupage. I sprayed the tops with sealer after they dried.
On the inside, I put a pin cushion on the top and a magnet on the bottom, to hold straight pins from falling out. Since the tins were too small to hold spools of thread, I included two bobbins with thread. I thought the tins would be useful when we do hand sewing at quilt club.
I labeled the tin bottoms with my friends' names and a graphic.
