Large circle cutter
Sewing machine threaded with coordinating thread
With a large circle cutter, cut enough circles (of 4-inch diameter or larger) from construction paper to create the desired length of garland.
On a sewing machine threaded with coordinating thread, first pull a long tail of thread for hanging, then sew one circle down the center on a straight stitch. Let the machine run a few stitches, then feed the next paper circle into the machine. Repeat to make the garland as long as desired, and finish by pulling a long tail of thread before clipping.
