I do not have one, and would only use one for special shapes, birds, butterflies, Christmas ornaments, animals..which I'd then use as fusables. Considering how often I'd be actually working them into quilts..I've come to the conclusion that it's not often enough to justify the price.
I really wish there was somewhere I could go to and rent the use of one.
In the meantime, I will be content to purchase them from Keepsake Quilting...or somewhere.
