Trade exhibitions for fabrics may be intimidating. Online, you may order fabric hangers from fabric providers. You could be charged by the fabric mill a fee, often between $5 and $10 per cloth hanger. Allow yourself some more time in case you come across fabric vendors that weren't included in your web search.
A lot of the fabric vendors that present at DG Expo are situated in the US, making it preferable for small quantity fabric orders. With more exhibitors, Texworld is a more major trade exhibition. Nowadays, most if not all fabric providers offer a fabric catalogue on their website.
Fabric vendors sometimes specialise in the products they offer, hence they frequently sell only a few types of fabrics. Begin assembling your samples in a binder together with their descriptions, costs, and sources of purchase. I advise utilising clothing that are similar to what you intend to produce as a reference.
Note any minimum order requirements. Furthermore, always double-check that they sell "retail" and NOT "wholesale" by reading the fine print. Some stores would advertise something as, instance, a silk cady at a high cost without disclosing that it is actually made entirely of polyester rather than real silk.
