REFERENCE REVIEW

Prepare a Yarn or Fabric Reference

Organise a visual, physical or technical reference with the information you already know, then continue through a Sample or RFQ enquiry.

Reference Draft

Technical review note. A photograph or document alone may not be sufficient to determine exact yarn construction, colour, denier, TPM or suitability. Physical sample review may be required.
