I've not used leaders/enders when piecing.. I don't notice any negative issues while piecing on my Juki straight stitch - such as bunched fabrics or thread nests - perhaps the auto thread cutter also makes it less obvious to need leaders/enders? Do you ladies use them for other reasons I may not be considering?
Macybaby, I bet your full-color scrappy will be wonderful - are you including any of those pretty Kaffe fabrics from the recent Boom?
JMoore - I keep thinking about your beautiful Arkansas Crossroads quilt you shared awhile ago - I hope I have the pattern name right. I quite admired that quilt and thought it would be a great way to use up leftover fabrics, too! Maybe it would be a nice future sew-along option?
I have two quilts to finish up and then I'll be cutting up a storm!
