How to Fix Bernina 435 puckered seams on delicate knits
If your Bernina 435 is experiencing puckered seams on delicate knits, locate the upper tension dial on the front faceplate tension wheel and verify it is set to 4. Incorrect seating of the thread within this assembly causes immediate delivery variances to the needle point. Adjust the component directly to lock in structural balance across the mechanism.

Puckering along fine knit edges often happens when the seam allowance is folded unevenly before passing under the presser foot. Utilizing precision tools like metric hem gauges for sewing helps you maintain perfectly consistent fold widths, preventing your feed dogs from unevenly gathering the fabric profile.
