I bought that stupid "add a quarter" ruler that is only 1/4" wide because it was on the supplies list for a paper piecing class. I used it for the very first piece of fabric and then decided that the 1/4" marking on my workhorse 5 x 24 inch ruler worked much better. Same class, same supplies list, I bought the "purple thang". If I'd known that my bamboo shishkabob skewers do exactly the same thing I would have saved that money too.
