20 gm cocoons
10 gm pure Lux Soap Flakes

Put a plate on top of cocoons to keep them under the water.

Take half an hour to bring to a simmer.

Simmer for 30 mins and they should feel squeaky clean.

If not, repeat process.

Cool slowly and then rinse and add a dash of vinegar to the second last rinse water.

Rinse a second time.

Leave wet and hang to dry, don't wring or squeeze.

When dry pull out to a square shape, 6"x 6".
