Removing Popcorn Ceilings -- will be glad I pinned this if I ever move to an older home and need to remodel. Don't ignore a house because of popcorn ceilings! They can be changed either DIY or painters.
Seashell paint makeover: spray paint inside of shells high gloss baby blue and paint outside with gold or silver paint. Maybe could do this with something else from nature if your home isn't beach themed.
