Sewing half square triangles / flipped ends
I have been sewing HST and flipped ends on blocks lately. I sit and draw my lines across from corner to corner while watching TV. I found several patterns lately I really would like to make but I just can't see myself marking so many lines. I know there has to be an easier way to do this. Because I have an eye problem in my left eye, I can't just wing it, it will be off. I know that there are easier ways to do this, help please.
