錐形螺紋轉接器

I've got three cones that used to wobble and unspool crooked on my serger, and these little adapters fixed it in seconds. They pop into the large end of the cone and hold everything steady on the spindle. Wish I'd grabbed them a year ago.

These adapters slid right into the large end of my thread cones and finally kept them sitting steady on the spindle. I use them on both my sewing machine and serger now, and rethreading goes so much faster without the cone tipping over.

The cone kept wobbling off my serger's spindle until I popped one of these adaptors into the large end, and now it sits perfectly still. Such a tiny, cheap fix for something that was driving me nuts.
