We used templates for some things like dresden plate wedges, applecore pieces, etc. Yes we tore fabric back then. I was working in a SewFro store when the first rotary cutters and mats came out. The cutters were yellow Olfa....thin, hard plastic handle that came in one size to begin. The mats were hard, dark green with no markings. They were shiny smooth on one side and pebbly textured on the other. I still have the cutters and the mat is now 4 small pieces I cut up for my grandchildren to use under their craft projects about 15 years ago.
