What it means

Selected backing is too weak or inappropriate for the chosen fabric/design combination.

Why it matters

Incorrect backing leads to distortion, shifting, and poor sew quality.

Common triggers

  • knit with tear-away only
  • dense design on unstable fabric

Typical fixes

  • recommend cutaway or stronger backing
  • increase support layers

Notes

  • Related to shop/operator setup and not purely geometry.
