Bloc-Loc's half square triangle rulers make the tough job of squaring up easy and fast. The groove slides along the seam to trim smaller units and allows quilters to rotate the block without lifting the ruler.

An easy, efficient & accurate method to square-up half-square triangles.  Align the seam of an unpressed hst with dashed lines and with easy strokes, trim all four sides.  The unique edge slots allow for trimming of the dog ears at the same time.  No need to rotate fabric to realign. Other uses include: square-up hour glass blocks, strip piecing of half-square triangles, strip-tube method of block construction and fussy cutting. Trim up to 11 sizes from 1 1/2" to 6 1/2" (Two trimmers allow for full & half-inch sizes).
