How much do you love half-square triangle trimming?
I usually find it to be necessary and chalk it up to part of the process, but there’s no reason we can’t be smarter in how we work!
I prefer to make the units slightly larger and trim to size, that way I know that they are perfect. And not because I have to make things perfect. Perfect pieces make sewing multiple units together so much easier, so I go through all the motions even when sewing on a deadline project!
This half-square triangle trimming tip is best applied when you are using a high-quality thread that doesn’t take up a ton of space in the seam allowance. My current fave is Aurifil 50wt. Line up the ruler on the seam as shown, and trim two sides before pressing open.
Since I had so many to trim, I put a line of tape on the ruler so I didn’t have to find the mark every time. If you are just making a few, find the unfinished size of your unit, and line up the ruler. These were trimmed to 3 1/2″
