Let your pattern determine the size squares you start with. As a general rule, you’ll want to cut your squares 1/2 inch BIGGER than you want your finished Half-Square Triangles blocks because you’ll loose some to trimming and seam allowances. The quilt I was making used the same two fabrics in all of the half-square triangle blocks, so I cut out equal numbers of my two fabrics.
You may be anxious to use your squares, but if you want your corners to match up properly, you really need to trim up your squares, so they are exactly the size you need. Most quilting rulers have a 45 degree line marked. Line up your 45 degree marking with your diagonal seam, so that they line up exactly. Trim your square.
And now you’re ready to add these blocks to your chosen quilt pattern.
