The Crumbler measures 5 1/2" from top to bottom and has markings that allow for cutting tumblers in at least six different sizes. There is a center line that can help with cutting side setting pieces or making pieced tumblers. Seam allowance markings help with fussy-cutting or cutting tumblers to different widths. The template comes with some sheets of paper that include: Instructions on how to line up the templates for piecing and pressing recommendations. Guidelines for cutting side pieces and fussy-cutting. Yardage information ~ or how many templates can be cut per strip for each of the possible sizes of tumbler. If I make this many rows with this many tumblers in a row… how big is my quilt going to be? That’s in there too.
