Onto the shower floor, at least.
Step 1: Assemble the Materials.
You will need:
-A lot/enough string. (A string that is soft, preferably, not too thin as it may cut throught the soap.)
-A bar of soap. Hm. Obvious. The soap can be new or pre-0wn3d, if it is new, wet it a tad and then dry it, it helps to soften the soap a bit.
-Scissors - To cut. No, not your wrists. Sorry.
-Something to drill with / A screwdriver (to make holes in the bar of soap)
-A hand. Please. You must have one.
Step 2: Drill Holes Into the Soap.
Probably should mention that you will need two holes, on either side from the sides of the bar.
one inch-ish should be good, less if you have a tiny bar.
Step 3: Stringing.
Tie these in a "grandma's" knot around, making two little loops.
Next, take a larger string and thread it through those two loops, as shown in picture two.
Step 4: Tie the String.
Tie it in a final loop, if you're minimalistic just do an average knot(grandma's) or you can be awesome and do a pretty knot, like in picture two.
Step 5: Enjoy.
Enjoy that now, with a cool soap bracelet you can look awesome in the shower.
