Here's a quick and easy project. This particular project is done with the 24 X 18 inch poster, but you could use any of the sizes that HM offers: the new 11 X 14, the 12 X 12 scrap pages, the 8 X 8 scrap pages, etc, depending on what you want to do with your wall. I love the vinyl lettering, but it doesn't transfer from room to room, and I like to change things around a lot, so this type of home decor is easy and transferable.
Design your poster/scrap page using pictures, quotes, etc. Then once you've received your order, mount it on foam board with double-sided tape, photo adhesive, or modge podge, and mount it on your wall with picture hooks. Easy. Of course, you can get more elaborate with it: ribbon, embellishments, etc., but sometimes SIMPLE is better!
Here's an example of the poster that will be going up in my daughter's room as soon as I get it, but there are tons of clever templates already in the template gallery, and I'm sure many of you are much more creative than I am! These projects are simple and inexpensive, and can add just the right touch to any room!
PS. If you're interested in this particular poster, leave me a comment or shoot me an e-mail. It's not in the template gallery, but I've got it, and would be happy to share it with you :)
