Ah shucks, thanks!
I don't know how much help I'll be when purchasing a new sewing machine! Mine is over 26 years old and I don't think they make machines like mine anymore...it's a Singer, completely mechanical, with one-step buttonholer and bobbin winding right inside the machine. No fancy bells and whistles, but a real workhorse. I have not looked at machines since I purchased mine, and I really hope I don't have to for a very long time. They are so expensive now!
Have fun with your crocheting!
