AprilM it is the Quilt in a Day Triangle Square Up Ruler 6 1/2", so you square them up before you press them. It is faster than after pressing them. I can't figure out with all the rulers I have where that one is. I did find I can do it instead with the Easy Angle, so I stopped myself from buying another one like the one I lost. So far it seems none of my granddaughters are interested in sewing, and I know I will never use it all up, though I am trying, so I don't know what to do with it if I go before it does!!!! hahaha
