Just wondered if that's a common problem for a newbie.

I think I'm progressing okay overall; only been at it a couple of weeks. The nicking of the corners on the rulers tends to happen when I'm bringing my cutter down and I guess I misjudge where the edge is. I did read one piece of advice to hold the cutter at a 45-degree angle and that helps some - provided I position it on the
fabric and not on the
ruler!
Is there any way to fill in the nicks? Right now they don't affect the cutting really; I'm just being a perfectionist

- kind of like when you get the first door ding in a new car, you know?
It's happened more on my small squares - mostly the 2-1/2" and a little bit on my 4-1/2".
Ah well, if they get too bad, there are always the 50 percent quilting notions sales at JoAnn's.
