Oh TammyTx even if I had a fancy shmancy machine (and I certainly don't) I wouldn't drag it to classes. I'd keep it safe at home. Yikes if all your gonna do is peice when you don't need the bring the Cadillac along.
And baustin check to see if there's a local quilt guild you can join. Maybe it will be a better group. We have a gal in our guild that is about 75. She like you took a machine quilting class at 70. She is one of the nicest ladies I've ever met and a great quilter to boot.
Unfortunately it sounds like you both had run ins with some quiltzilla's. Don't let that stop you from looking into a local guild. I'm one of the youngest in my guild. We have ladies that only hand quilt, some that only machine quilt, some that only do applique quilts, and everything in between. I always look forward to guild day and seeing and talking about all the things we've made.
