I am going to have my room freshen the paint in belated March for my fourteenth birthday and I am hoping for some ideas for colour scheme, cool things to have around approaching notice boards, lava lamp... links to websites would be good.
I enjoy a large pane, two built in cupboards, a desk, a bookcase, a bed and a dartboard if it make a difference.
My favourite colours are purple and blue and I am going to paint one of my cupboard doors next to blackboard paont.
I want to swot up how to sew...how...
Answers:    My grandaughter is 14 and we did a WYWO
last year when she go away for the weekend.
We used purple.aqua,white and lime green.
All her tv stand is siler and glass.
Her little table were painted a color surrounded by the color palette of the said colors.
We made the headboard.
The comforter,rugs and curtains were purchased at WalMart.
We added beaded stuff on the curtains.
A crystal beaded shade is over her ceiling bedside light.
Both grandma's are artists so we did sets of canvasses painting for her.
She's into Tinkerbell so she has a couple of pics of that.
Looking for a form that states my contractor...
How give or take a few a vase of copy flowers for your windowsill? They'll last for , brighten up the room and you could buy colours that will clash your colour scheme.
