I made my own template yesterday for the charm square size. 3.5" was the template and the lines 1" in .....looking at it I think the bigger template is 6.5" and I'm going to just follow the lines out from that and cut the square smaller to make a smaller one... this is experimenting but I refuse to pay for something I can only use for twisters...DH will either cut me some acrylic or as I'm short a 3.5" ruler will buy one and mark it.

The 8" tool uses 10" blocks, the 3½" tool uses 5" blocks, the 2¼" tool uses 3½" blocks and the 1½" tool uses 2½" blocks.
can someone confirm what border sizes the twisters uses, I've read its a 6" border, the smaller ones must have tiny borders, the moda 2.5" blocks would be good for the tiny tool although cutting.
I'll get busy with the drawing and see if my calculations match up with someone else's large twister, then we just reduce it for the smaller ones I reckon.
