For me if it depends how many I am making.
I like this method of getting eight 3.5" HSTs from an eight inch square if I need to make heaps of them
Like for my Lady of the Lake quilt blocks recently
But if I'm only making a few I just make them two at a time.
I like to starch my fabric for HSTs too so that the bias edge doesn't stretch.
I know some people like to use thangles or other methods, what method do you use?
