I love Shrink Projects! You just color in the designs and then use either a heat gun or your oven to shrink them. They start out thin and then get smaller and thicker. Great for Ornaments or Keychains. Great for Zipper Pulls too. This set has pre-printed designs that you can just color in and blank pages. I love the blank pages as I can use my printer to make my own designs and then color them in. I use colored pencils. Kids love to make these!
