It's amazing how cute those letters can look! I saw theseblocks and had to have them, but not without my own twist (of course!). I printed out her original letters and modpodged them on the back so that if I decide I don't want the purple and green later, all I have to do it turn them around.
Here's her printables, but with the color changes I made, just in case you wanted a little more color too.
After making these I of course had to have some fun scallop banners to add a little more color around the house. I got the pattern here.
