The set must be put up for retail sale as a unit, contain woven fabric and yarn together, and be intended for making rugs, tapestries, or embroidered articles. If the components are sold separately or the set is not retail-packaged, each element is classified individually under its own heading.

No. The heading explicitly allows accessories to be included alongside the woven fabric and yarn without changing the classification, provided the set is still packaged for retail sale and intended for the specified needlecraft purposes.
