DS bedroom

[HouseHuntingNoMore]

Hi
What are the best sites to look online for inspiration in decorating DS new bedroom? I've looked on Mothercare & Kiddicare but need ideas for colour schemes (am thinking blue & green - it is a big room) & curtains etc etc.
Thanks

Next and John Lewis and I'm confused because I've replied to this twice now .

I tend to recreate a Next bedroom but with just a few items from it rather than the over the top rooms they do.

For both my sons, different room schemes but bought the curtains, lightshade, duvet cover, wall stickers. I match a Dulux mixer paint colour from something on the duvet cover to blend in.

I tend to paint the whole room but in the case of my eldest son his duvet cover is predominantly pale blue, the paint colour is also pale blue to match but then on the curtain wall I picked out an accent colour from the duvet cover otherwise the curtains would just disappear into the wall colour wise.

My two boys are 6 and 3.

Thanks you both
TBH I do not know if I am coming or going & am sorry that I may have asked a similar Q before.
Thanks again
