I am always reading with interest the reviews. I normally use rotary cutting/sewing techniques so I have no bias edges exposed and I also use ever tiny bit of fabric. I guess I worry about it taking me back to working with tiny pieces of fabric and waste like before rotary cutting and when templates where used. Ofcourse I can see this is much faster and way more accurate then templates. It is wonderful if you have issues with cutting. So eventually I will need one too unless one of my children cuts everything.I use mostly the special quilt in the day rulers for 1/2 triangles, flying geese etc. I would love to play with one though. For now the cost and maybe not knowing what I am missing will keep me from getting one.
