Pale sage green I think would be nice, with a gray knitted or woven blanket.

I agree with MMEPATTY, don't "match" per say...go with a vintage vibe instead. Gray, or just the right shade of robin's egg blue, and then go for it with funky pillows.

Solid color sage comforter/duvet, and buy another drapery panel to make pillow shams and a bed runner (like they have at fancy hotels, to dress up the white duvet). That will bring the color over to the bed and pull the room together.

OMG those match my stuff perfectly! I bought sheets from target's Dwell line, they were green and yellow and brown polka dots. My mom made a quilt with those colors plus lots of orange (cause I was obsessed with orange and elephants). I redid our glider in the same sage green as the sheets, Unfortunately I bought all this stuff/made 3 years ago. Does someone sew and can make you a duvet cover their are lots of tutorials out there right now.

First off, adorable. Second, I would go with a duvet in a solid color (or at least a large, unfrilly pattern, like stripes). Purple comes to mind.

Love bedding challenges. For the crib:

The Zid Zid bedding for Land of Nod incorporates the orange, green, and the playful animal theme: http://www.landofnod.com/baby-crib-bedding/kids-bedding/sleepin%27-safari-crib-bedding/f5092

Dwell Studio bedding in the new Woodland Tumble pattern would blend but downplays color for neutrals. http://www.dwellstudio.com/designer-baby-boutique/dwellstudio-collections/woodland-tumble/woodland-tumble-nursery-collection.html

Pottery Barn Brooke would work for a girl: http://www.potterybarnkids.com/products/brooke-nursery-bedding/?pkey=rromnurbrk

Their Harper nursery bedding is preppy but simple and brings in that lovely green without competing theme wise. This would be the easiest to match for the full bed I would think. http://www.potterybarnkids.com/products/harper-nursery-bedding-green/?pkey=rromnurghp

For bedding I think crisp white with green or seafoam green with white or cream sheets-

These are white and green- grass green edge on white-bedding

Or this seafoam green duvet and shams with white or cream sheets, mix and match with the shams -

another seafoam green-

Then a throw that is the same orange as the drapes in a small herringbone print

This rug to pull all the colors together, I love stripes with other prints-

The Anthropologie Rivulets set is on sale right now:

So cute - love the direction you're headed- definitely a child's room but not overly babyish. I love the idea of an off white or dove gray duvet cover with a colorful throw at the foot of the bed to tie in the orange and/or green. West Elm is having a flash sale on duvet covers and shams today so it might be worth checking out their website.

Where are these curtains from. I am dying for new orange and beige/white curtains... i have a bit of an orange obsession.

@WCHH - first line of the post. They came from Anthropologie.

I would suggest this quilt set from Target, it is a nice mix of orange and green and should really bring out the green from your artwork.

I have a queen sized bed and I prefer to use a king quilt or coverlet.

I like stripes as a contrast to the curtain pattern. How about these green rugby stripes from Pottery Barn Kids:

@BEEBALMJ - Awesome suggestion!

I like this pebbles and fish set!

Sorry thought this was for a baby! Goes to show how closely I read... how about this
I like the orange blue color combo.

For a REALLY coordinated look, Get another set of drapes and make a duvet cover. Or use that extra set of drapes to upholster a headboard.

Otherwise, DwellStudio and Serena and Lilly seem you first stops.

I also like the idea of using a khaki bed cover (so maybe try Pottery Barn Kids or PB Teen as well as Land of Nod)... or a large-scale khaki and white (or off-white) stripe (Dwell, Ikea, West Elm, or Marimekko).

If you DO bring in a color not already in the room, art or curtains, you're going to need some textile to make sense of the total package, but that could be as minor as a throw or pillow.

With large scale patterns, I always recommend small scale or solids to coordinate. Avoid a second large scale pattern - it will fight. And for the love of pete don't buy the exact same pattern for your bed... SO boring.

I would not add more green, otherwise it's just more matchy-matchy with the art. I'd go with indigo blue -- a bit brigher than navy and about the same hue as the deep orange (hue is the amount of grey in any color that brightens or mutes the shade). You might consider a fun large-scale chevron pattern since the room seems to be playful. I love this one from Urban Outfitters.

PS -- then throw a green pillow on the bed to tie it back to the artwork.

I would add a chocolate brown duvet cover or a light cafe au lait duvet cover with a pillow or pillow shams made with the same fabric as the curtains.

Um, I don't think making a duvet out of the same drapes is sooooo boring. Depends a lot on the size of the room though. And I'm not sure that a second largescale pattern *wouldn't* work. I mixed a Marimekko pattern, a large-scale patterned rug, striped walls and a striped throw in a recent nursery, and it totally worked. They all need a common denominator (in mine, the same white in all patterns) and some patterns were geometric, some organic.

Also, check out the nurseries in Sarah Richardson's projects... she's taught me textile/pattern bravery!

Everything is so cute. I would go for a navy blue comforter.

I would go with a cream colored bedding, that way you can add some fun pillows, blues greens, maybe even a soft yellow? this way you can change the pillows, and change the whole look if you desire. Good luck, love the curtains!

You can't go wrong with plain green.

thanks everyone for the great suggestions! I should have also mentioned that we are using crib bedding from our first which is the dwell chocolate dots. I am now thinking of going with a solid teal duvet cover with green accents.

something like this in aqua: http://www.urbanoutfitters.com/urban/catalog/productdetail.jsp?id=20570149&color=105

blanket: http://www.serenaandlily.com/Bedding/Blankets-Throws-Apple-Herringbone-Throw

and then fun pillows to pull it all together. something like this from Anthro has all of the colors, I can pair that with an orange and green pillow
