ChiaoGoo End Stoppers
Use end stoppers to put projects on hold, or set aside stitches to be worked later. Kits come with a single pair of these useful items, which is rarely enough for knitters who like to have more than one WIP on the go. I like to use them along with short cables as a way to set sleeve stitches aside in top-down sweaters - that way I can screw in my needle tips when I'm ready to work the sleeves and get straight to knitting.
Chiaogoo End Stoppers are a long rectangle, which makes it easy to screw these in quickly.
The screw join on Chiaogoo end stoppers come in 3 sizes, Mini, Small and Large. Be sure to select the size that matches your cables.
