I bought some at the International Quilt Show in Chicago. They had a wonderful demonstration. It was what I would call a bit "pricey". And to be used for very specific areas. it is designed to shrink 30 percent in all directions. THe demostration I saw , said not to use the 30 percent as a constant expectation. They said their experience was more 25 percent.
I think there are some tutorials out there , Check the Superior Threads site . I know Alex Anderson has one on her new web based site called "the Quilt Show" it was a free one , not part of the subsriction services. If you can get to a quilt show where Superior threads is a vendor they are very , very knowledgeable on this new product and have wonderful samples and demonstrations.
Note I just checked There are three tutorials on Texture magic on the "the Quilt Show site" . Below is the first in the series of three. They are free.

I will try to find the link for both.
Very cool stuff , just wish it was not so pricey so I could play with it more.
