What you needFelt
10 x 5" cardstock
Cut a 10 x 5 rectangle out of heavy weight cardstock.
Cut a 3 inch circle in the top as shown.
Do the same thing with felt but make allowance for sewing by adding a fraction.
Cover your cardstock with the felt and stitch around the edges. Alternatively you could glue this felt on and cover the glued edges with ribbon, glitter paints or cord.
Once your door hanger is covered you can embellish with ribbons and ornaments.
