You've seen bobbin storage systems at the local sewing shop, but those are meant for smaller bobbins. What about the M-class bobbins used on your longarm? How about putting them in a tree? A Bobbin Tree, that holds 30 bobbins! Genius! And Exclusively from Handi Quilter. (Plus, who doesn't love purple and lavender?)
Oh, and if you've got some smaller bobbins hanging around for your sewing machine, they'll fit, too.
Bobbins are not included.
