The Clearly Perfect Slotted Trimmer is an efficient tool that makes it easy to accurately square up half square triangles. Tool allows you to trim all four sides of half square triangles and dog ears without having to rotate your fabric.

Dashed lines are for aligning your unpressed half square triangle seams to then easily trim all four sides. Trimmer can also be used to square up hour glass blocks, strip piecing of half square triangles, strip tube method block construction and fussy cutting.
Features:
You will notice that there are two sets of rulers that come in a package. One ruler is for Half Square Triangles that are FULL inches. The other ruler is for HALF inch increments. I can not think of a better or easier way to make Half Square Triangles than using these Slotted Trimmer rulers.
