I'm afraid this is a really stupid question, but here it is! Can you make half square triangles eight at a time like Bonnie shows, but without using that specialty ruler? I have an easy angle, companion angle and all kinds of square and rectangular rulers and would like to not buy more. But I'd like to use the eight at a time technique. If anyone could walk me through this I'd really appreciate it. Or, should I break down and get one of the rulers she suggests? Thanks!
