CocoKnits Stitch Stoppers - Jumbo
If there were ever a time to use stitch stoppers, it is when using jumbo yarn! There was nothing to help keep those extra large stitches on the needles.
Cocoknits tip: The centers of the stoppers might be big enough to use for your smaller knitting needles! Poke a hole in them and pop them on your small needle tips, rather than toss them out!)
