Anna Wulick of forty-two roads creates a baby art wall for her DIY baby nook by using willow branches as picture rods.

I like how the artwork is an inch or so out from the wall and thus functions as a kind of mobile. I used two willow branches and some recycled ribbons to hang up artwork that is mostly from Etsy. The collage all the way on the left is made by me, however. Yay! This little corner makes me happy.
