Sue,
I'm beginning to think we are sisters from another mother! Both lefties and both gouging the June Tailor.
JUST last night I went to watch the JT demo videos because I was sure there was something I was doing wrong. I watched them all and noticed that when the woman puts the blade in to start it's on an angle and then she straightened it up when she starts cutting down the channel. I plan on trying that. It think we might be ever so slightly off of straight when using them and that's causing the problem.
later sis!
