Don't be in too much of a hurry to sell the machine and the contents of the travel bag. I don't think the machine has a lot of value, but with the other items, the value goes up, imho. It sounds like a package that a new quilter would love to have. Good luck with your sale, and I hope someone who is just starting to sew--quilt will give it a good home. That is my hope when I am gone and my girls sell my "stuff". I told them not to throw anything away, but find it a good home. Three daughters and none of them sew--pity isn't it. I know I haven't been a lot of help, but I know your mom would be happy with what you are doing.
