I have several sizes of the twister....they are fun...I think they shrink at least 1/3 in size if I remember correctly. I do think they are fun....when I made the bedsized one with the largest template, I did it at the local quilt shop so I could pushe the tables in the classroom toether as the top was pretty big before I cut it....the smaller sizes are fun...but kind of putzy....and I had to use the smaller sized router cutter on them.....the woman who invented the technique lived near me and I visite that little shop often...it has closed now...I miss it...
