I would love to be able to make a "Happy Birthday" banner with the letters for my upcoming daughter's birthday. If you have some time, try it out! Post a comment and pictures if you are successful at the rag quilt or rag quilt letters!
The steps to making the rag quilt letters and numbers can be found at Oh So Happy Together.
If you have more time, try making this full rag quilt at I Can Teach My Child.
