It's hard for me to pre-prepare that much. Honestly. I have a few quilts going at all times and wishing I could start the next, but the leaders/enders thing is not part of that picture. I don't like cutting so much I guess, and that would be where I would have to put concentrated effort to keep up I think. I bought a new throat plate just for piecing with one hole instead of the wide slot and as long as I use that I don't need the spider or leader/ender piece, but I do love the little nine patch pieces that I saw. What a wonderful bonus!
