The stickers will be just as helpful and useful as our GEasy Ruler Stickers, and just like our GEasy Ruler Stickers, they are reusable and do not leave a residue behind. The stickers come with three colorful sheets that feature 2 sizes of numbers (1-13) and Letters (A-M), common cutting sizes, and blank stickers to organize your quilting projects. They are great to use on wonder clips in the regular and jumbo size.
