I love Terial Magic. I buy it by the gallon on Amazon. I use it instead of starch before I cut my fabric for piecing. It's perfect to prevent bias edges from stretching. My hsts and other bias edge cuts fit perfectly together block to block. I use for machine applique, no wrinkles, fullness or puckers at all. Most all the machine embroiders in my guild use it instead of the stabilizers normally used. That's where I learned about it. The tee shirt embroidery is so soft and moves with the fabric not stuck to it like a sticker.
