6. Troubleshooting
This section addresses common issues you might encounter with your Dritz Sew You Adjustable Dress Form.
- Difficulty Adjusting Dials: If the adjustment wheels are hard to turn, ensure no fabric or debris is obstructing the mechanism. Apply gentle, even pressure. If persistent, a small amount of lubricant may help.
