There's something magical about a seat that sways. Eva Brittain, 9, thinks so too. So last spring she showed her mother a photograph of a rope-hung daybed and asked if they could build one. Mom Angi, a contractor, happily obliged. "Eva sketched it and I tweaked the dimensions," says Angi, who added details, such as bracket-shaped supports and armrest cutouts for cup holders. Construction was a team effort, with Eva tracing the shapes onto cedar, Angi handling cutting and assembly, and Eva sanding and staining the piece. Now that it's finished, even older daughter Claire, 13, is in on the action. Says Angi, "It's everyone's favorite napping spot."
