This is great! THANK YOU
I was shown many years ago to pull up the bobbin thread. cross it corner to corner, hold it down with the guiding finger and follow that line.
I have a piece of painter tape on my extension table that I use for sewing my 45* angle. I line from the needle and sew aim for the edge of the painters tape. There are several ways to avoid drawing lines. Jenny Doan irons a crease in her squares and sews along the crease.
Thanks for posting, I also hate drawing lines.
I have done this and have sewn the cardboard to the fabric.
Not a bad idea, but I have also done the folding method, the thangles, and pencil line. It depends on my mood.
