Even when I used a very scant .0.25 inch seam whensew8l ng hsts from squares cut to the size suggested - I end ed up with too small hst units.
Very scant t0 me - is between 1/8 and 3/16 of an inch. I actively dislike the scant 1/4 inch seam direction.
Use whatever seam allowannce that achieves the desired finished size. There are several examples of using three strips to check - thickness of fabric, thickness of thread are also variables.
if I cut the triangles separately , the hst units ended up closer to expected size. When cutting around a template - assuming the template is the exact size - a teeny bit of fabric is added while the piece is being cut out.
I press my hst units with the grain. Both directions.
i am in the wash before cutting group. I want to know how the fabric behaves without the sizing.
Starching does minimize fraying and the back of the top stays a lot neater.
