So, how do you make soap on a rope? It's really easy, and lots of fun! If you already have a favorite soap recipe, start your soap making like you would normally do. You will also need about 18 inches of some kind of rope.
The easiest is to use melt and pour soap and add your own fragrance. If you have a double sided mold that snaps together, you push both ends of the rope down into the opening so that they will be about halfway into the bar of soap. You want to make sure your soap is firmly attached to the rope! Put some rubber bands around the mold as extra security to hold it together, and pour your soap into the mold, overfilling slightly.
If you are using a one sided mold, again start your soap making in your usual fashion, then pour your soap into the mold so it is about half full. Let it set up just a bit to form a film, then lay the ends of your rope on top of your soap so they will be at least halfway encased in the finished soap. Finish filling up your mold by pouring the rest of the soap over the top of your rope, making sure the rope doesn't float.
Place your soap where it won't be disturbed. Let your soap harden as you normally would do before removing it from the mold. Voil, you have soap on a rope!
You can also make soap on a rope from a regular bar of soap and mold it with your hands. Turn the bar of soap into soap flakes by grating it (or using a food processor). Add enough water to make a dough and knead it with your hands. (For 3 cups of soap flakes add about 1 to 1 1/2 cups of water.)
Tie a knot in the ends of your rope to hold them together. Put a few drops of vegetable oil on your hands so the soap dough won't stick so much. Form a ball out of your soap dough and push your knotted rope down into the ball about half way.
The artistic minded can mold the soap ball into different shapes using your hands. Set your completed project aside where it can dry at least overnight. You now have your very own soap on a rope creation with soap making!
