Making your boys bedrooms different and exciting may seem hard but isnt really.
Your theme for a boys room should probably come from yours boys and what they like.
If your son has a favourite sport or team then this is pretty easy.
That probably wont apply to younger children, so use favourite colors or animals that they like as an inspiration.
One point to remember is to leave room to grow with the child.
Or do it in such a way that its easily changed as your boys and their tastes change.
Make sure you talk to your child and be sure (as much as you can) that they will like the new space and style being created for them.
