Getting use to holding it as fairly small but having tried to make small circles by freehand - not good regardless of practice - this ruler is remarkably easy and accurate.

I put some gripper stuff on the back to keep it from sliding and love it. I find it easier to go inside a circle than around the outside, used it for a thin border on my quilt.

LOVE my Pebble templates! I didn't think that I would need the smaller ones but wow, what a difference it has made with my circles! I am currently working on a very whimsical quilt and I am having so much fun with my different sized pebbles, I almost wish the quilt was bigger. :) (For slipping, I haven't had that problem, but I have found that PMQuilting Slip Stop is awesome. Highly recommend it for all rulers. )

ProPebbles are great for detail quilting. It is super easy to see the marking lines on all types of fabric.

These are the best small circle rulers by far! And have crisp clear markings
