Bloc Loc Flying Geese Square Up Ruler 2.5" x 5"

Bloc Loc’s Flying Geese 2 1/2″ x 5″ ruler locks onto seams for instant ruler placement, control so that the seams end in the corners and trims the correct amount across the tip. No more wobbling, either! Once the unit is completed and trimmed, it will measure 3″ x 5 1/2″. Trims full & partial flying geese, parallelograms, square in a square and many, many other versions of flying geese units.
