I participate in several postcard exchanges. I keep a book of postcards so when I travel and teach classes I show people the wonderful things that can be created with only a few supplies and a sewing machine ( or by hand sewing). My book has now runneth over...so I have been trying to find some more creative ways to display all these little artful cards.
As you enter our home I have two baskets sitting upon a hutch that my dad made that are full of postcards for our guests to look at and a really cool metal photo tree (container store about 15.00) that the postcards clip to and hang from. Then my favorite of all is in our bathroom we have a photo shower curtain that holds 4" by 6" photos...perfect size for postcards. The shower curtain is my favorite because we can change it out with different holidays or themes.
