Step 1: Decide what the fabric is going to be used for
To help narrow down your search and to choose furnishing fabrics that are suitable for the purpose you want to use it for think about whether you are using the fabric for curtains, cushions, blinds or as an upholstery fabric.
Not all fabrics are suitable for all uses. For example, if you are using a fabric for upholstery it needs to be hardwearing. It also needs to comply with current regulations for upholstery, this may mean that the fabric is inherently fire retardant, has already been treated or can be treated. If in doubt check with us or with your upholsterer. Curtain fabrics need to drape beautifully so needs to be of a suitable texture and not too stiff and rigid. Some fabrics, for example, silk fabric, drapes better when interlined as well. See this article on the Martindale rub test for information on upholstery fabrics.
Curtain fabrics are usually also suitable for making into cushions and roman blinds.
