18x18 Throw Pillow

What the face does and where it stops

The finish and the tight weave on the face make water bead and sit on the surface for a while instead of soaking straight through. That buys you time, and time is genuinely useful: a drink knocked over on a patio chair can be blotted off before anything reaches the inside. What it does not do is stop water that sits. Given long enough, or given rain driven at it, moisture works through the seams and into the fill, and fill is the part with no way of drying quickly. A pillow that gets properly wet stays damp inside long after the outside feels dry.

• Blot immediately, do not rub. Beading only helps while the liquid is still on top of the weave.
• Seams are the way in. Water finds the stitch line before it finds the face.
• Stand it on edge when rain is coming. On its side, water runs off rather than pooling in the top seam.
• Bring it in for storms. The fabric is built for splashes and damp air, not for a night out in the weather.

Sun is the other outdoor variable

The same face that sheds water still takes ultraviolet light, and light is what actually removes color from a printed pillow outdoors. A cushion under a covered porch or a deep overhang keeps its artwork far longer than the identical cushion on a chair that catches direct afternoon sun, and the difference shows up within a season rather than over years. Rotating pillows end to end evens out the fade so one side does not go pale while the other stays saturated.

• Shade beats treatment. Position does more for color than any fabric finish.
• Turn them regularly. A pillow that always faces the same way fades on one face only.
• Store them out of season. Somewhere dry and dark, standing rather than stacked, so the fill keeps its loft.

Indoors it is simply the sofa size

Most sofa seats run twenty one to twenty four inches deep, and an eighteen inch square is the smallest that still holds that corner upright on its own. It sits at roughly shoulder height against a standard back cushion, which is why it reads as furniture rather than as an accessory.

• Sofa corners and armchairs. It fills the depth without pushing you forward on the seat.
• As the back layer. Put a 14x14 pillow in front of it for the size step that makes a corner look arranged.
• On a bed. Standing in front of sleeping pillows, it holds its shape rather than folding forward.
• Same artwork, either size. How the print behaves once the square is filled is covered on the printed pillow page.
