For soap on a rope you will need
2 cups soap flakes
1/2 cup tap hot water
yarn or a cord (we use baling twine)
Looks like cheese
You need to grate your soap. When I was in town,I checked and I didn't see any bath soap flakes, and you don't want to use the laundry soap.
Cut you twine or yarn to fit loosely around the neck. Lower to mid chest, and tie a knot at the ends.
Pour your hot water into the bowl with your soap. You can add food coloring to it if you want. Squeeze like meatloaf until it forms a ball. It will be sudsy.
Break the ball up into however many you may need. (we did two, then combined the excess of these to form a third)
Wrap around your twine. Squeeze it firmly to adhere to the twine, right above the knot. Squish into cookie cutter or free hand sculpt.
(These are the boys prototypes. They forbid me to show you the finished product in case the recipients of the gift happens to see this blog. Medium made the Christmas tree, Small the dog, and Large made Mr. Hanky)
Allow to dry for several days. Once dry, tie a knot above the soap.
And a warning. Even after scrubbing your hands, soap still seems to cling under your fingernails. Be careful not to wash your mouth out with soap. It really doesn't taste that good.
