Trimming Half-Square Triangles
Trimming half-square triangles is another story! I despise trimming, but thankfully there are wonderful tools out there to make the job a bit faster.
There are two specialty rulers I have tried and would highly recommend either of them!
Bloc Loc Ruler– If I had to pick one, the Bloc Loc would be my favorite ruler for trimming half-square triangles. After pressing open your half-square triangles, the diagonal line “locks in” and holds your block in place so you can quickly and accurately trim and spin your blocks. It really speeds up the process and makes for very accurately sized half square triangles. The only downside is each size needs its own ruler and can get pricey. I bought this three-pack, but use my 2.5″ bloc loc the most.
Clearly Perfect Slotted Trimmers– This ruler comes in a close second. It is definitely the fastest way to trim half-square triangles (I timed myself haha!). Before pressing your blocks open, this ruler lines up on your sewn seam and guides you where to trim and clip corners. It is made for multiple sizes, making it a great deal for the price! When you press open your block is then done and ready to go! It took a bit of getting used to and I would highly recommend wearing a cutting glove, but if you’re in a hurry, this is the ruler for you! The only downside to this ruler is it is a bit less accurate. Because it doesn’t lock into place, if the ruler slips as they tend to do, your block may not be exactly 2.5″.
