why does Jenny do this?
I was taught and I am sure many others were too, that you never use the marks on the mat to cut your pieces, always use your ruler. Well I have watched several of Jenny's tutorials (MSQ) and sometimes not always but sometimes she uses the marks on the mat. Don't get me wrong I love her and all she does for quilters, but why does she do this? One of the things I love about her is that she does not intimidate new quilters.
