M-style Prewound Bobbins #515 - Purple Dozen

Keep your longarm stitching smooth with our M-style prewound bobbins, each wound with 187 yards of lint-free 60 wt. polyester thread. You will spend less time winding bobbins and more time finishing the quilts you love. Each bobbin has ~70% more thread than self-wound bobbins, meaning fewer bobbin changes. Longarm quilters call our prewound bobbins a true game-changer. This strong thread runs cleanly through your longarm and pairs beautifully with 100 wt., 60 wt., 50 wt., or 40 wt. top threads. Includes 12 prewound bobbins.
