I haven't been able to sew enough with any of the machines I own to have a favorite but I'm fondest of my W&G! She was love at first sight!!
but the machines in my home are as follows:
My mothers Singer Touch & Sew 758 (which sadly I think is beyond repair)
Brother LS 1217 ( which is currently a love hate relationship as I try to get her to behave. She was gifted to me.)
Eleanor my 116 year old Willcox and Gibbs Automatic Chain Stitch treadle
Tucci my 1952 Singer Featherweight (adopted from original owners son)
Flower my recent adoption of a Brother XR6060 (simple computerized machine with 60 stitches!)
As you can see my collection is nothing fancy but I've only been sewing little things. Maybe if the quilting bug bites hard I might look for something fancier. But for now I'm pretty impressed with the XR. She's very smooth. But my love is with the vintage and antiques!
