I’ve been using this trick to save my scraps and make half square triangles while I’m at it. It’s a great method to use when your adding stitch-n-flip corners to a block.
Lay the square in the corner of your block with the pencil line like so:
And stitch down the line as you normally would. Instead of trimming and throwing that whole corner away, sew a second line ½" away from the previous seam towards the corner like so:
Then cut in between the 2 seams:
Press, and you’ve got your block with the triangle corner, and a half square triangle.
The half square triangle will be 1" smaller than the original corner square you sewed on. So this corner square was 4", and my half square triangle is 3". This is a great trick for patterns like Pow Wow where the corner squares are large and it creates a lot of waste.
Then you’ll have lots of little tiny HST’s to make another project!!! Because all you needed was another project right??! ;)
