Light colored fat quarter
Freezer paper (found in the aisle with the tinfoil)
A computer and printer
Step 1: Cut your fat quarter into 8.5"x11" rectangles, the exact size of a sheet of computer paper. You should be able to get four out of one rectangle. Cut out 4 rectangles of the same size from the freezer paper.
Now you can sew the tag onto your fabric; I use a tight zigzag around the folded edges. Enjoy your machine washable fabric tags!
