This is easy enough to figure out. Cut some heavy paper into 6" strips (maybe 1/2 or 3/4 wide). Start sewing with a bright thread (red, orange, green...whatever you like), and start feeding through the paper strips with 1" gaps in between each. So festive. Would look lovely with blues/white for Winter or red/green for Christmas too.
