I was thinking the same thing the other day when I bought a packet of those non-slip dots for the back of my ruler. The lady at the LQS told me it came with enough dots to outfit a dozen rulers. Yeah, I have 1. lol. (Plus a triangle ruler, so I guess that's 2.) But there are other things I can't imagine doing without. How on earth anyone can get perfect shaped circles without Karen K Buckley's "Perfect Circles" tool is beyond me. I spend way too may hours trying to get just 1 to work before I gave up & bought the tool. God bless all those old-time quilters that did everything the hard way! The more tools I acquire, the more impressed I am by their skills.
