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.
