Sure, visit Office Depot, Staples and purchase the sheets of magnets, cut to fit the size you need and glue the back on using Fabri-Tac. Also look in your real phone books for the attorneys that use these magnets to hold their ad on; these are FREE

here in the netherlands you can buy a magnetic tape. One side is with glue so you can glue on backside, the other side is the magnet.

Gayle, that sounds like a great magnet - why don't you just use a satin stitch around the outside - then use your pinking shears to cut around the edges and glue a magnet on the backside.

Depending on the size you can use a can lid or a canning jar lid to attach it to.....cut a circle and use a running stitch....add magnet....hope this helps.
