Should I prewash the fabric to remove sizing before painting using Fabric Creations Soft Fabric Inks?

Yes, all fabrics should be prewashed using soap and water following the manufacturer’s washing instructions. Most denim fabrics should be washed multiple times in hot water to remove thoroughly the sizing in the fabric. DO NOT use liquid fabric softener or dryer sheet as doing so may prevent the inks from adhering to your fabric properly. If your garment is wrinkled, you may iron the fabric as instructed on the garment label; however, DO NOT use spray starch as that, too, may prevent the ink from adhering to your fabric properly.
