Many thanks, PatriciaDrew and JeanneS -- your help and mentoring are so appreciated! I'm going to check out all your suggestions. I'm going to take it slow in getting used to this new machine. I'm currently piecing a top made of many many HSTs; I'm thinking I should probably finish it with my current machine for consistency's sake. At the same time, I'll play around with the Juki so I can get the hang of it; maybe I'll try to quilt this top on the new machine if I feel up to it. (Now to find some videos showing how to do wavy lines with a walking foot ...)
