With my new serger. My old one---a Singer "Swear-o-matic" was beyond a pain to thread. When the foot pedal was submerged in the flood I didn't even bother to have it repaired. This was my Christmas present to myself and one of the best things I've done for myself this past year. It is, as promised, a dream to thread. Not just the loopers, but the needles! What a pleasure. I'll be making a lot of garments with the help of this little sweetheart.
