Mommo Design has a bunch of inspiration for girly reading nooks. These quiet corners contain fluffy pillows, rugs, cushions, usually a canopy, and of course lots of books. I think the idea is very cute and I'd love to do this for my daughter's room.
If you're looking for DIY spring decorations, there's nothing better than butterfly crafts! Create a hanging mobile craft and surround yourself with the pretty and delicate creatures, just like in this Cascading Butterflies Mobile!
