Quick fix: Always pick up each colour from the same side consistently — one yarn from the left, one from the right. This prevents them wrapping around each other as you work.
What you are seeing
Your two working yarns twist around each other as you knit, creating a tightening tangle that eventually locks up your work and forces you to stop and untwist.
Why it happens
- Picking up yarn from different sides randomly
- Turning your work and not untwisting the yarns
- Yarn balls rolling together and wrapping around each other
Fix it now
- Stop and untwist. Give your work a turn in the opposite direction from how it twisted.
- Going forward: always hold Colour A from the left and Colour B from the right. Never swap sides.
- At the end of each row or round, check if the yarns twisted. If so, drop both and let them unwind before continuing.
Prevent it next time
- Use two separate yarn bowls or project bags, one on each side
- Wind both yarns into cakes so they don't roll together
- After every few rounds, drop both yarns and let gravity untwist them
