designmuse I have been lucking finding girls' bedding at Pottery Barn Teen. They have more options than the typical pink stuff. I have also found things on Overstock.com. Cute room. Good Luck!

housemamma How about simple a simple off white or white,(depending on furniture color) fluffy comforter. My daughter has a white duvet cover that can be washed. Then you can add throw pillows in the yellow or green ranges. Depending on her age, some "fake fur" pillows might be fun.

How about bedding which introduces another color?

EB Interiors I would definately take a change from the green and yellow. ..you need to break it up with fresh white duvet and fun throw pillows...

EB Interiors also white pique window panels

Marie Hebson's interiorsBYDESIGN Inc. Hi hnks, Marie here.
I think you need to get right away from any more green and yellow - its vibrating.
Bring in chrome, cream, whites, maybe another saturated colour - like purple something to ground it.

I realize the mood board below may be a bit too mature for your daughter, but maybe try black and white bedding? Or Purple with bright white - if you do introduce more green - make it richer, darker not so bright. Good Luck!

bellandromeda green and pink is a good combination, you can try this out, they've got green walls but the furniture stands out.

pollyannagal White bedding with a textural interest such as pin tucks or ruffles would be lovely and fresh in this scheme. Fold the green blanket across the bottom of the bed and add a few deeper green cushions or white ones with a very simple green pattern (leaf or maybe gingham).

Please don't be tempted to put any more yellow in as that would throw the colour balance right out. You have several shades of green which work well with just one shade of yellow but would look overwhelming with more colours. Introducing additional colours or patterns in the bedding would look messy, especially as she will no doubt add lots of other pattern and colour with all her stuff.

P.S. That has got to be the thickest mattress I have ever seen - it makes me think of the fairy story about the princess and the pea. I bet your little princess sleeps well on it!

olldroo Definitely white curtains and bedding it will look really fresh and sharpen the yellow and green and give the room a young look. I would like to see the curtains fuller too. Love the colour of the furniture. .

olldbobbi You could tone down the green a bit with white paint and some natural elements, like wood. Or white with touches of turquoise.

Donald I'm going to vote all white bedding too. The bonus if everything is white is it doesn't all have to come in a set, you kind find things with different textures...crisp white sheets, fluffy comforters, cotton blankets, furry pillows, etc. maybe even monogrammed in green.

bdennison if your daughter is set on the walls and curtains, go with white or pale lavender bedding. Lots of room to jazz things up from there

feeny A little green and yellow go a long way, and you have a LOT of them. Definitely no more "matching" colors. You need accents. Others have suggested good options--either toning down with whites and creams, or going playful with pinks or purples or even oranges. Here's one of my favorite teen rooms with greens and oranges:

michigammemom I agree that the intense green is overpowering the room. I would suggest bedding like this Rainbow Dot duvet from Pottery Barn Teen to lighten the room and add some contrasting pops of color. You might also consider white window treatments.

Design Mode I think you need to get a different boxspring (8" shorter) or just a support board, to bring down the height of the mattress. It looks awkward and takes away from the design of the bed.
Then you could repaint the yellow to green, the lightest stripe colour. If your daughter likes yellow, use it so it has more impact, in the accessories and bedding. I would include hot pink as the main accessorizing colour, then yellow. Really, I'm just copying from a great room that Samantha Pynn did a on Pure Design, HGTV, which was all green with small touches of hot pink. The circle wall art was a do-it-yourself project for the girl. You can watch the entire episode on this blog. I like the rustic-crafty stuffed animal.

hnks I agree that the mattress is really high and looks awkward. She does like it but I can talk her into removing the box spring and getting a support board to bring that height down.
I love all your ideas. Thank you so much. I am going to look for white with a bit of purple since that she loves purple. Oh my, monogramming a pillow is an awesome idea!

bdennison Happy shopping with DD.

mytwoandmeis3 @pollyangel etal: That matress is fabulous! Just like one my parents gave me as an adolescent and it provided me with more than good support...I felt like a princess. I would have let my mom take it from me too, but I'd silently been sad.

hnks Here is an update, we got the bedding and need your opinions so far. Took me almost 2 months just for the bedding... Wondering how long it will take to complete the room...
Thanks!

olldbobbi Looks good! How old was she when you started? Just kidding. Can you move the bed and nightstand a bit to the right, so the nightstand covers the outlet? Personal peeve of mine:))

hnks Haha! Come on, I am being fast here. :-)
I thought about the outlet when I was putting the furniture. I felt that moving the bed and nightstand towards the door to hide the outlet would make the room look and feel smaller. No?

olldbobbi Of course you're being fast here! I'm still working on a two-year old project, so in comparison, you're doing great! In my defense, it did start out as a simple bathroom redecorate.....

I can't really see what's on the other side of the room, but I would want the bed centered on that wall if possible. If the outlet is exposed it would drive me crazy, that's all. Maybe she has a large stuffed animal that could sit with it's back to the nightstand, kind of whimsical? I have a 50 year old teddy bear that's seen more homes than Carter has pills!

pollyannagal Looking good. I would move the bed as oldbobbi suggests - far from making the room smaller it will open up a nice area between the bed and the window. Put a comfy reading chair or beanbag here (pink?) and a desk in the alcove so she's got a little space for drawing/ homework/dressing table (don't know how old she is?!). Kids love the feel of a semi-private space within a larger room. She's a lucky girl. I would have loved a room like that when I was little.

olldbobbi pollyannagal, you're so right, she's a lucky girl! Right before I turned 18 my mother redid my bedroom - in yellow dotted swiss! I do believe she was trying to tell me something.....

olldroo What a difference. The curtains are still bugging me. If she really likes them, then that is fine although I would prefer a white sheer, but can you get more of the sheer to make them fuller. They look a bit untidy, sorry, and are dragging the room down.

hnks Indeed, she does like semiprivate area. I am sure she would be too excited with a bean bag. Thank you ladies so much. I do have that corner as well for a desk. She wants a white one. Oh and she is 10 years old.
