Joanne, a friend of long standing (sounds so much better than “an old friend”, don’t you agree?) who has a consignment shop in St. Louis, sent me this simple idea that an resale, thrift or consignment shop could use:
I was at Target yesterday and I found these place mats that I used to display some items.I thought everyone on your list might be interested. The cost is $8.00. You get 4 different spring colors and it adds a bright spot to any dark areas and brings you eye to the items you have for sale.
Look at some shots she sent along:
Thanks, Joanne, great idea! (And folks, don’t forget to check out place mats, doilies, and so on in your local nonprofit charity thrift store to stock up your display supplies!)
