Dinghies and sleighs make good seating. Some finds are only meant to draw the eye and impart playfulness. Put an old mantel against any wall you think needs some interest for an instant oddball focal point. Add a window in the fireplace for a surreal kick. Set a gargoyle in front of your chair as a footrest.
Vintage clothing is often beautiful but unwearable display it instead.
Slips and textile scraps in gorgeous fabrics make wall hangings or window treatments. Meals and playtime will benefit. Set off the furniture you already have. Iron garden gates, mounted on a plain bed frame, become unique head and footboards. Add texture to your ceiling or a wall with discarded molding.
