I'm making a mystery quilt and I just ran across some instructions I've never seen before. I hope I can write this so that it makes sense. So, keeping in mind that a flying geese block is made from one rectangle and two squares. I've always drawn a line down the middle of the square, stitched across it (corner to corner), then folded it up. The parts underneath (the corner of the rectangle and the corner of the square) get cut off leaving a 1/4" seam allowance. So, the instructions I'm using said this:
"We like to keep the base piece (the rectangle) intact for accuracy, so trim to 1/4" on the B patch (the square) only. This is sometimes called a sew-and-fold corner. Repeat for the other side."
So I took that to mean that I should fold both the rectangle and the square back, and cut just the middle triangle. Get it?
My question is this: how does that help for accuracy? Is this the usual way to make a flying geese block? Maybe I've been doing it wrong? What say you, oh wise ones?
