A few months ago a friend of mine brought me a simple wall hanging. It had been made by wrapping several strips of fabric around a stretcher bar frame, and stapling the fabric to the back. She asked me if I could make some of these for Festival of the Trees. FOTT is an arts fair where our quilt guild (and many other entities) sell their goods to the public. (It is always a big deal in the small community where I live.)
So I ended up making 12 of these wall hangings, using mostly decorator-weight fabrics. It was actually fun, just sifting through many different fabric samples and sewing strips into larger pieces. I used 9" by 11" stretcher bars and my trusty staple gun.
These little framed pieces can be hung either horizontally or vertically with simply two little brads.
The two below could be sold as a set.
Then I also made a few with Christmas fabrics.
I don't think a tutorial is necessary. It's a pretty simple process. You could whip up a few of your own for some of your holiday decorations.
