When I as at Quilt Camp one of the campers came with pre-cut tumblers. She used an Accucut at her LQS. I loved them. And because the dies pre-trims the corners they are extremely fast and easy to piece and there are no dog ears to trim. Oh yeah, and they are super FAST to cut:)
So I combined both of these items and pieced and quilted this quilt yesterday.
