This set has 12 elaborate butterfly designs. These have all been digitized specifically for use with mylar to add sparkle to your project. Several of the designs work particularly well with variegated thread for additional highlights.
This set also includes the simple instructions to help you make a cardigan-style jacket from a regular sweatshirt. This set would make a beautiful wall hanging as well.
While it is difficult to photograph the "sparkle", the designs below are actual sewouts.
