What do you use to measure out your 10" and 20" circles on target paper?

I got mine from a local supplier who happens to sell on EBay.  They don't offer the 10" on EBay, but will make one.  I got the clear polycarbonate (vs plexiglass), 10" x 1/8" thick which is plenty stiff (thick).

I think you will find their shipped pricing very reasonable and they accept PayPal.  It was also well packaged for USPS.

I found a clear plastic tray for a pot that used for plants.
89 cents at Dollar General.

The plexiglass is great, but here's a cheap and quick alternative for the 10" circle.  Take a 31.5" piece of heavy gauge wire, I use aluminum, form a circle and tape the ends together.  When drawing the circle, I place a ruler across the top to hold it down.

I use the top of an old styrofoam minnow bucket... I like the idea of plexi glass

I've been using a 10 inch diameter clear piece of plexi-glass for years and I've found nothing better.   

I had a plxi-glass donut made, 10 inch cirlce cut in the middle with the OD of 20.  works awesome.  found a guy on Ebay that sold plxi-glass and asked if he could make me three of them.  thing all three were like 40-50 to my door.

This is what I use. Jim of Warbird turkey calls made it for me. I can't do the 20" circles. but it takes care of my 10" circle quite nicely.

I use this 1/4"X10"
