I used them yesterday cut 6 layers of flannel worked great.

I am super excited! My rulers arrived yesterday and I am sewwwww IMPRESSED!! Thank you, Thank you 'feffertim' for posting about them!!!

So glad you like them. I think they are wonderful.

Thank you for posting this... I just tried the Simplicity Rotary cutter and it was terrible. I spent time getting all the alignments and it cut ok, but the guide was not long enough so when the material went off the glide it did a dip in the material and therefore the strip was wavy. I returned it immediately. I think this could solve my problems.. Looks great and thanks for all the feedback.

My slide lock rulers shipped today! The shop is only 90 minutes away so it shouldn't take long.

Well that was fast. They arrived!! They must have shipped yesterday. I got the email today but only saw they were shipped and didn't read when.
