Please don't stop quilting. Having too many tools can be a burden sometimes (ask how I know). Buy specialty rulers only if you intend to make more than 1 quilt using them. There is always a way to make a quilt without using additional tools. I hate using templates so I have lots of specialty rulers. I've been quilting about 2 years and have only used a fraction of them. I'm considering selling some of them, just need which ones can do double duty.
