Well, all I've got to say is that I've been missing out on this for years - I don't know who dreamed up spray basting, but it's wonderful! I've done all the quilting on one quilt today with no fabric shifting, no repositioning of pins, and it's all a whole lot lighter and easier to handle in my sewing machine! I'm never going back!! I'm sure the even feed foot has something to do with it, too - but whatever it is, I'm loving it!!
