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. Trim up to 6 slotted sizes: 5 1/2" to 10 1/2" (Ten 1/2" sizes). This larger ruler is used for trimming 1/2" sizesonly.
Other uses include: square-up hour glass blocks, strip piecing of half-square triangles, strip-tube method of block construction and fussy cutting.
Please note: although these trimmers are manufactured by the same company as some large, well-known ruler companies, they are a little more delicate because of the slots close to the corners. Please take extra precautions when handling. To be used with a rotary cutter: use at your own risk.
