Picture from Pellon
I decided to give it a try. The material is like a thin plastic that you can trace onto, and then sew to the back of your fabric.
It is set by steam from your iron. You hold the iron about an inch above the Fabric Magic and it shrinks it up. Although it doesn't look like the plastic is changing shape at all, wait until you turn it over to look at the fabric! Total shrinkage.
The more quilting or stitches you make in it, the more it shrinks up. If you sandwich batting between the fabric and the Fabric Magic, it gives it even more of a 3D look, and we all know how I like my 3D embellishing!
Here is a little peak of a project I have made. I can't reveal it yet because there is some exciting news to go along with it, but just to keep you interested....
