I stopped by a friend's (she doesn't actually write on the blog, though :)) the other night and she was working on house decor. I asked her if she'd take a few pictures for me to post here for the "Make Your Own" theme. Very easy (from the sounds of it) and very inexpensive!
The frames were $3 each at Ikea and the fabric totaled $4.50 - not bad! She just took little nails and nailed the fabric into the frames. You could also use a staple gun if you have one.
