the casserole carrier was a hit with my brother , made with the U of M fabric . he tailgates at the games.
so my thinking would be, if you make things out of your states pro-teams, they may sell well.
also items for cats and dogs..or items made from cat or dog material. snap bags seem to sell well..different sizes.
