Oh I feel your pain. You have all the pieces lined up to sew happily away and then THAT happens. UGH. :evil: It's usually been the bobbin for me too.
Country Quilter--I watched a man work with my sewing machine once and saw him unscrew the bottom--so now between copying him and following my book on where to oil I do my own. Not near as often as I should :roll: ...but it's nice to not have to be without my machine for any amount of time.
