This is indeed the Best Ever Knots Off Silk!
NEW VERSION with 24" silk and improved instructions.
You take a silk and tie a knot in it... then slide the knot off the silk.
This can be repeated again and again!
At the end the silk is shown to have 3 large holes in it! Surefire laughs!
You can even have an audience member help tie the knot and even slide it off the silk.
