Personalize thrift store glasses. Spell out a name w/ stickers. Tape off top and bottom. Dab acrylic paint lightly over the stickers and untaped area. Apply 2 coats. Unpeel and you're done! You could do the same thing with etching cream. (Plus other thrift store glassware update ideas)
A trick for hanging photo collections: Lay out your arrangement. Flip frames over. Lay waxed paper on top of frames. Mark hanger/nail spot on waxed paper. Flip waxed paper over and tape to wall, nail into wall where indicated. Tear down waxed paper. Hang photos.-- Found this ONE day after I spent HOURS hanging a "gallery wall"
Shoes on wall hooks. Keeps them off the floor, out of the way but still easily accessible. Could run more than this along or up a wall.
Dip paint stirrers or paddlepop sticks into each of the pain colours used in your house and attach on a ring. If you are out shopping you can make sure items match you decor before buying them. You could also add fabric samples of your curtains, couches etc.
