I purchased at Wal-Mart a plastic case that is intended for small toy cars. The case is customizable so your walking foot would also fit. It doesn't need to fit in your drawer, you can lean it against your sewing table, that way it will be near to your sewing machine. The case also protects the presser feet from damage. I bought several platic cases for my presser feet for my machines and in my opinion, the toy car case is the best.
