There is a Studio die that has the following circles on it:
3/16" (.5 cm), 7/16" (1 cm), 9/16" (1 cm) and 11/16" (2 cm)
the metric measurements are from the Accuquilt site, not my calculations. They don't give prizes for finding errors, I've tried
If you want to see a visual of the difference, go to accuquilt.com and search for die # 50232. On the monitor, the difference is quite noticeable. I wonder about my ability to draw anything so precisely.
Rita is right, it will take some tweezers to get those tiny ones glued down.
I will be looking for a stencil of circles to the 16th inch (for the circles that are not on any accuquilt die), at my local art and graphic supply store. I think that "steadler" does one. I'll let you know what i'm able to find.
