We wanted bright colors and shapes for our little guy's room.
Eclectic and colorful
Crib: Pottery Barn; Dresser: Target; Bookshelf: Target; Chair: Ikea; Lanterns: Luna Bazaar; Changing pad cover: DesignsbyChristyS Etsy Shop; Curtains: DIY; Wood Letter: Eddie's Lab Etsy Shop; Paintings: Stephanie Hoffman; Rug: DIY, rug from Walmart, stripes Rustoleum Spray Paint
I love the rug, mostly because it was a project I took on with my best friend. We saved almost $200 copying one I found online. I also love the ikea chair with ikat pillow and hand knitted blanket made by my mother in law.
Do as many shapes as you want, but try to stick to the same exact shades of color.
