We discovered yet another use for unwanted Christmas cards and/or gift cards.
Use crafting glue to attach each end, leaving some room for the "tab" to have space behind it.
Allow it to dry.
Attach a "tuck-in" such as these embellished paperclips. Tuck in a tiny gift, or clip it to the tab.
Use larger pieces to create a "pocket" for the card for other "tuck-in" gifts. Decorate with stickers, markers, glitter, scrap fabric, trims, or even tiny buttons.
