Here is a few things you can do for the livingroom, familyroom, or even a den.

• Go to your nearest grocery store and buy a small boquet of flowers. I bought one for $6.99 and used in 3 small vases.. It was white daisies, red carnations, and dyed blue mums. Add in a few flags and a few 4th of july picks. They look wonderful on the mantle or even on shelves, or tables.. It is a very cheap idea with a lot of impact..
• Cover all of your throw pillows with homemade pillow cases (check back to mother's day for instructions on how to make them.) cut some fabric for tableclothsor runners. If you like you can even make a scarf for your windows...
• Add some artwork with flags or even the capital. Whatever you can find that reminds you of the 4th..

I hope this gives you a few ideas.. Tomarrow I post a few pictures of my familyroom and hopefully they will help you with even more suggestions...
