Slip Sliding Away: Slippery Yarns

I am currently knitting True Friend with some incredibly slippery yarn.  Allegedly wool, though I can't be sure as I can't read the labels (in Chinese) and the slipperiness is really making me doubt my original judgment on the wool content (which, admittedly, was just guesswork to begin with). 

I got myself into a bit of a pickle when I was dragging the project around, not being careful enough.  I had the working end coming from the center, and the outside of the slippery, slippery skein started unravelling.  The two ends tangled, and I spent precious knitting time picking the ends apart and winding them back up.

The offending ball...

The offending ball...

So that got me thinking about ways to hold together a center-pull ball made of slippery yarn.  Someone makes mesh "yarn bras" (I don't know why that term makes me shudder so much) which are basically like the mesh that fruits and vegetables come in.  I've done a DIY yarn bra; I find the one from a three-packof garlic is the right size for a typical yarn ball.  It worked well but the mesh started getting holes after a while (for what it's worth, the ones that you can buy look more robust than my DIY ones) and also the plastic mesh is slippery and can let the yarn free.  I've also seen people use old pantyhose -- you could just cut the foot off an old pair with runs (as an aside, is there anything you can't do with old pantyhose? https://thesecretyumiverse.wonderhowto.com/how-to/18-awesome-ways-reuse-old-pantyhose-0138241/ https://www.rd.com/home/cleaning-organizing/pantyhose-uses/ http://www.apartmenttherapy.com/20-interesting-household-uses-for-old-nylon-hose-stockings-212234).  And my last idea was a zip-top bag, with the zip unzipped just enough to let the working end of the yarn through.  And the ball inside the bag could twist and turn as much as it wants.  So far I've settled for winding the outside end very firmly around the middle of the center-pull ball, tucking it in tightly, and being very careful when I manipulate the ball.
