I love her book, I've read it a lot while we are building my new quilting space after a move. But my bed risers have disappeared!! DH found then, asked what they were and immediately put them under the legs on one of the sofas.
I'm not getting them back... four inches makes a big difference in the ease of exiting that sofa and we are not getting any younger (kind of ugly tho - sofa does not have a skirt.
