Bloc Loc Flying Geese 2" x 4" Ruler

The Flying Geese Bloc-Loc rulers are specifically trimming rulers and have a 1/4 inch channel or groove at the back which firmly hugs the 1/4 inch seam allowance of the pieced unit, allowing you to trim all around for a perfect Flying Geese unit; no measuring is required for placement of the ruler nor does the ruler shift/slide when cutting. Placement of the ruler is quick and accurate, every time.
