I have had the same blue idea for several years and just recently started running with it.
My main colors are:
Some of my favorite themed items:
|My "No Name" board|
|Supply Organizer for all of my little odds & ends|
|Storage shelf underneath my teaching white board|
The fabric for my curtains was a clearance fabric at Walmart ($3/yd? Yes, please!) and fits well with my theme and our class mascot- the dolphin. Yes, we are near the mountains of Colorado and our mascot is the dolphin ;)
