This package of 10 plastic sheets are part of the Shrink Prink collection from Dress My Craft. The sheets are size A4, 8 1/2" x 11 3/4". These sheets allow you to create embellishments, flowers, tags, jewelry, book covers, mixed media and more. You can use these sheets by first stamping an item and then shrinking it with your heat gun, a toaster oven, or a regular oven to the desired size. These sheets can also go into an inkjet printer for printing the images needed, or they can be run through your die cutting machine. On average, these sheets shrink to almost half the size. These papers open up a whole new way of creating embellishments and come in a wide variety of colors.
