It drives me crazy trying to find the end caps for my knitting needles. I take them off to knit, and when I set them down inevitably one slinks off to hide somewhere. So I tethered them. I pushed safety pins through the flared edge of the end cap, then clipped the pin to a hair band. When I’m ready to knit, I slide the hair band on my wrist. When I’m done, the little rascals are right there.

My safety pins are a little different; they came with a knitting kit, so may actually be stitch markers. They have a nice sharp point and will go through the end cap material. A standard safety pin would work as well. I do recommend using a stretchy bracelet type object, so there are no clasps to undo. I don’t recommend using one of those silicone bracelets with the friction clasp, because the clasp is likely to pop open as the bracelet is pulled off and send the end caps on a merry flying trajectory across the room. (Yup, experience.)
