Looking for a ring pillow? Try your sewing box. A pincushion makes a charming one that's just the right size for little hands. A vintage pincushion like this is particularly nice, but you can use a new one, too. Then all you need is a long decorative head pin, ribbon, and your rings. Thread ribbon through rings, and tack ends to cushion with pin.
