I can't take credit for this BRILLIANT idea. I saw it on a website (for the life of me can't remember which one). The girl had used circular scrapbooking tags. It was really cute.
I was a little short on time and decided to print off a whole bunch of homemade tags. I used the Avery 8160 Template and just put thick card stock in my printer. I made three sheets. One for Queens, one for Kings, and one for Twin. Then I punched a hole on the outer edge of the tag. I wrapped raffia around the sheets, and put the appropriate tag around each bed sheet. Now there is no longer the guessing game as I change the sheets! Have Fun!
