Each girl should decide how many swaps she wants to make. This is the same number that she will receive. She may make them all the same, or make every one different. If you want to make some swaps for a camping unit, then each troop should make different swaps so the girls are not limited in trading. If you are making swaps in your troop, give the girls an assortment of beads, small wooden shapes, paints, markers, ribbons, felt, chenille stems, etc. and let their imaginations go wild.
Swaps are usually only an inch or two in size.
Instruct the girls to create their swaps with a safety pin attached. Swaps are traditionally pinned on a swap hat. This hat could be part of your troop identification. Perhaps painters caps in your troop color. Remember that swaps are made as tokens of friendship.
