Upholstery - Slipcovers
Slipcover fabrics need to have a high weight to strength ratio so that the slipcover is light enough for you to wash it in your home machines or carry to a cleaner.
If the fabric you want to use is not pre-shrunk, you’ll want to wash before fabrication to take all the shrinkage out before fabrication. (There is no reason to wash our fabric before use except to remove shrinkage. We use no chemicals of concern at any step from field to finished fabric, so there is nothing to wash out.)
