Tangled, runaway yarn isn't bad luck. It's that none of the usual fixes actually does the job:
A yarn bowl stops the rolling. It doesn't stop the twisting.
The ball stays put, but it still can't rotate — so every loop you pull adds one twist to the strand. Twenty rows later those twists become the knot you spend ten minutes picking apart. The bowl solved half the problem and charged you full price.
The tote bag is where tangles go to get worse.
Yarn in a bag rubs against everything else in the bag. You reach in for a clean pull and come out with the strand wrapped around your scissors, your hook, and last month's project.
The mug trick lasts until stitch four.
Your phone leans on a mug, the screen times out, you tap it with a yarn-covered hand, the phone slides, the mug moves, and now you're rewinding the video to find the stitch you were on. Both hands are supposed to be on the work. One of them is always on the phone.
Holding tools "somewhere safe" means losing them.
The stitch marker is in the couch. The 4mm hook is in the other bag. The snips are wherever the snips are. You stop mid-row to go hunting, and the flow you sat down for is gone.
It isn't that you need more discipline, a bigger bag, or nicer yarn.
it's that nothing you own spins the yarn, holds the phone, and keeps the tools — in the one spot where you actually stitch.
