Book Boiling ?

Since retirement The Fuzz and His Sweetie have become involved with this Art Journalling class at a local studio.  Over the Holidays the project was "Book Boiling".
So, what exactly is this "boiling" of books?  You may well ask.
It does involve hot water.
First the papers were cut and folded into what will become the "signatures" of the finished books.

The idea is to place vegetation of various sorts between what will eventually be the pages of the book.

Then this is tightly clamped together and dropped into a pot of boiling water for an hour and a half (or more).
This does take a while, so while they were boiling away there was pot luck dinner, and time to catch up on other projects.

When the bundles are taken out, the plants have dyed the paper in various ways.

Since they have been folded together both sides have been colored.

The paper is then left out to dry for a while.

Here's some of the ladies admiring their work.
