Swap items, especially tags
Way back when shipping was more reasonable, I joined all kinds of swaps. Swaps are when a group of people decide to each individually make a bunch of the same item, then everyone swaps so that each person has a variety of different items. I still have many swap items that I have not used because they don’t fit with any of the scrapbook pages I have done. I’ve learned that using them for cards is a great solution. Simply add a border, or eyelets/brads in the corners – put the tag in the center and you’ve got a card. I’ve made many, many quick cards this way!
