I just gave this a try and it's great! I've been working on a 4 patch scrappy quilt for ages and I'm now working 4 patch units into the border. I got stalled because it's pretty tedious, but sewing the 1 1/2" units as leaders and enders has gotten me going again. Now I need to cut a bunch of pieces or strips to leave by my machine so I'll have them ready. And, the best part, when you cut that leader off it's like a little gift. I never thought I could work on two quilts at the same time. Thanks for pointing out this tip!
