Mizkyp and Woodland Creature, how wonderful to be in the place to purchase a new machine for your classes or travel. I have loved my retirement sewing and have made significant progress in using only from my stash or purchasing only what is needed to finish a project. I count it one of the privileges of being out of the career race. Time to relax and enjoy our fabric.
I have a featherweight that travels with me and after 7 or so years hasn't given me one moment of problems. A perfect machine for my purposes. Enjoy your new machines and sewing projects. Show photos of your projects so we can rejoice in your retirement fun!
