Hi, Judy,
Hopefully, you'll get some more answers from those who have tried them, but I wanted to let you know that if you go to the product page for the 3-D Butterflies, and you click on 'Download Information', you'll get a zip file with two very informative pdf files in it.
One is from the manufacturer (Dalco) explaining the technique with pictures, and the other is a beautiful project by our very own Diane Brown that uses the butterflies in a very creative way and gives full directions.
Hope this helps.
