Painted the nursery for my second daughter this weekend (first daughter pictured). 3 walls are green and one white with polka dots. The idea was inspired by this picture.
The stenciling was done with acetate film taped to the wall. I'd cut 5 stencils (3 little and 2 big) and reused them for each color. This worked OK, but the paint drying on the acetate ended up stretching it so that subsequent colors were harder to keep the edges from bleeding. I'd bought some temporary spray adhesive but unfortunately it didn't seem to work on the acetate.
For paint I used the green from the other walls plus 3 of those little color samples they sell at the hardware store.
