Simple DIY! The dollar store oftentimes has gorgeous flowers, thrift stores always have vintage frames, and for those who want something a little sturdier than cardboard for the letter, Michaels or JoAnn's carry wooden letters in all sizes!
Easy DIY Disney silhouette pictures that I made for my daughters room. Dollar Store frames, Google "Disney Princess Silhouettes", find the ones you like, print and cut out, select your own paper for background (I used scrapbook paper), glue and frame! (I used sparkle acrylic paint on the silhouettes before I glues them to the paper for a little more sparkle!)
