So for a 10 in. square the template or ruler would be 8.5?

yes.

any ruler will work :thumbup:

Exceptional.

Just beautiful...I can't wait to begin ! I own a little square ruler I hope it is this size... will check ...about to run downstairs. . .

I wonder why the marks,the 1 inch and the others are 3/4 inch?

They should all be the same distance from the corner. ie: 3/4 inch is the right measurement.

When the lines are set up on the seams of the squares the sections of each of 4 squares are cut on a precise angle...then when rejoined in a layout to form pinwheels the entire piecing is all pinwheels all in the same 4 parts of a like square. . . amazing to see happen...and beautifu l to see finished.. . .yet not a tideous process to have so many odd shapes joined and Joyfully so quickly as well...a one day project for sure you'll be so excited to show to others or gift. . .as a table topper or wall hanging if artfully chosen colors of fabric... Some (usually solids),just stand out among the others so neatly... Look at someof the links. For Twister Tool or pinwheels tool . . .

What a Smart Idea!!! I like how you used the clear tape then marked the ruler

Looks great...I've since seen that the measurements are 3/4 " off each corner . . . regarless of the size...But I like your shapes, I think that is the tip--- we can vary that and experiment, for many unique shapes. . . I sure have enough fabric. . . (all we need is 4 colored blocks sewn 2 x 2 then bordered to get our sample of the finished shapes !
A shop called www.PrimativeGatherings.com 'has permission' to make and sell a template to make miniatures ! They specialize in all that is done in Wools,' hand dyed' there, best seen. and all else that's quality. . .perfect place to look at things and shop for 'country theme' sewing, hooking, quilting gals. and yes, like me, it's in Wsiconsin. . . the origin of the Twister Tool is far North in Wisconsin, too . . . I'll only make, for personal use, sizes she doesn't sell. . . they are not a big wealthy business . . . When they are at shows they sell their tool for $5 . . .only 2 products in the whole booth ! sizes for 5" Charms & 10" Layer Cakes.
