This is the Perfect Circle™ mylar templates made by Karen Kay Buckley. Whatever size berry or cherry or circle you need - it is here. There are several circles of each of the sizes. I made my berries on the Austin Bluebird Sampler with these - and this package of Perfect Circle™ templates along with the Bigger Perfect Circle™ templates (which we also carry) made all the circles for the Polka Dot Garden quilt. These templates will be able to be used over and over again.
