if i were doing it again i would not have gotten the crib set. mine was like $200 and it only came with 1 sheet, 1 skirt, 1 valance (how many rooms have 1 window?), a quilt, and a bumper. the quilt and bumper have been in the closet since i got them. i went nuts and ended up getting the matching lamp, throw blanket, rug, nightlight, and other valance, and now i think his room is way over the top and too matchy-matchy (i even had the throw pillows and basket liners on my registry, thank god nobody bought them!).
if you like a certain set of curtains with matching lamp and accessories, why not just try to find coordinating sheets and a skirt? that's what i wish i had done.
