Fill the centre with whatever stitches you like using whatever you like - floss, silks, metallics, beads, etc. Cut out, leaving a small hem. Make a cord and tassel.
WRONG sides together, slip stitch through the buttonhole stitch. You don't need to stitch through the fabric. Stitch the two short sides together first and then stitch along one of the long edges as shown, folding the humbug in half.
When you get to the corner, attach the cord by slip stitching through it.
Stuff the humbag. You should have a stuffed square with a cord at the opposite end to the opening.
Now slip stitch the opening closed as shown so the first seam comes to the middle of the remaining long side.
Attach a tassel or beads opposite the cord. Your humbug should look like this!
Attach to your scissors or hang on the tree...
