Very fun to use!
The Heidi Swapp Mini Bird Mask was the first HS mask I had ever attempted, and I had so much fun with it!
The branch and bird are two seperate pieces, so you can set the bird on the branch however you wish, or use one piece and not the other. I am currently working on using only the branch on a Halloween layout.
You can make the look your own by experimenting with painting over it - dry brushing, foam brushing, sponging, etc.
The back side of the mask is just barely tacky - just enough to hold it steady on your paper, but not sticky enough to damage your work upon removal.
Though I've not yet tried, I think it would be very easy to trace the mask as a stencil if you actually wanted a paper version of it.
Overall I think the Heidi Swapp masks have a great deal of potential and look forward to adding to my collection and getting creative!
