One of best things I did for myself is take a beginning rotary cutting class at a LQS. The teacher was very thorough and taught safety, maintenance, and how to cut accurately. I found out some tips that really were great. The class was not expensive and not a long class. However, I found out most of my mistakes in quilting were not in the sewing stage but in the cutting stage. Also, if you can join a local guild or just a group of quilters you will learn a wealth of tips from them. One thing in common with quilters is that they all like to share! Seek them out. It is worth the time.
