I have many notions myself and love them all and find all of them helpful in each way. I like my big ruler that has an edge on it to hold on to the edge of my cutting mat so I can stack my yardage and cut straight long strips even. That has been a life saver and a time saver for me. Also, love those little sticky pieces of sandpaper that hold your ruler from sliding. I guess I put too much muscle in my cutting for if I didn't have those on some of my rulers I'd only cut about 3/4 of the fabric straight:))I'd say the biggest waste of money is the chennile (sp?)cutter...the one that slides under the layers to cut for you. Since I was going to use it on a rug that never worked out...it still sits in it's plastic:))Maybe one of these days:))Skeat
