Look for a medium to heavy weight, densely woven cotton or linen fabric that provides good coverage. You don’t want to see through it! Make sure your white fabric is durable and stable so it can be washed over and over again without pilling, shrinking or wearing thin in spots.
Here are five of my favorite white slipcover fabrics:
White Topsider Bull Denim — Hands down my favorite white denim right now. This 12 oz. cotton denim is tightly woven and stable, which gives it good coverage and a substantial look. The white color is just right, not too bright or too creamy. Shrinkage: 6″ per on yard length and 3″ on the width.
Heavy White Denim Upholstery — A 14 oz. optic white cotton denim that feels more like a 12 oz. No problem! It’s still durable, very densely woven and has a crisp hand-feel. Expect it to soften up a bit when you pre-shrink it. Watch for small random flaws. Shrinkage: 3″ on a one yard length, 1″ on the width.
12 oz Cotton Canvas White — I like this heavyweight duck cloth (canvas) for simple white slipcovers that get a lot of use and frequent washing. It’s a good choice when lighter-weight white fabrics are not dense enough to cover dark colored upholstery. Shrinkage: White 3″ on a one yard length, 2″ on the width.
12 oz. Brazil Linen White — After washed, Brazil linen takes on a lovely casual look, floppy drape and softly crumpled texture. Just like a good-quality 100% linen should! I like the 12 oz. weight. It feels substantial without being stiff or coarse. Works well for both tailored and loose fit slipcovers. Shrinkage: 5″ on a one yard length, 4″ on the width.
All fabrics listed above are machine washable. Be sure to preshrink your yardage before making your slipcover even if the fabric is labeled “pre-shrunk”. To avoid deep set wrinkles be sure to pre-shrink your yardage per my washing instructions.
