During my latest IKEA trip, I has found a few items that would fit nicely into a travel-themed nursery. And, like most IKEA things, they're a little more budget friendly than you might find elsewhere.
PJÄTTERYD city art, set of 3 for $19.99
PREMIÄR world map, 78" x 55", $149.00
EIVOR LEVA twin duvet cover and pillowcase, $39.99
