Whenever you open an older book in the library and find the paper on the inside of the cover has been “marbled”, have you ever wondered how it’s done? Probably some complex industrial process, you might guess.

But actually it isn’t. It’s a fairly simple procedure requiring only a bit of practice and a flair for creating the patterns. Here’s what you need to get started :

* Some marbling ink — obtainable from most craft outlets.
* A tray big enough to take your paper, whether letter-sized, A4, or bigger.
* Paper — not varnished or shiny.
* Some newspaper to lay out the wet sheets.
* A paintbrush, stylus, comb or feather to create the patterns in the ink.

The process is simple.

* Fill a flat-bottomed tray with about an inch of water.
* With a brush or eye-dropper put a splash of ink on the water. It will spread out quickly in widening circles.
* Drop in other colours and experiment twirling them around with a comb or stylus.
* When satisfied, place the paper carefully on the liquid surface. Wait for about one minute.
* Hold one end of the paper and draw it up and out of the liquid.
* Wash the paper under running water to dislodge excess ink.
* Place the paper on newspaper to dry.
* When completely dry leave it under a few heavy books overnight to iron out the wrinkles.

There are many variations on this craft as you can guess, and I found five or six excellent books on marbling in the local library.

This is a really interesting craft if you have an artistic temperament. Home-marbled paper is also a good conversation piece. Some artists even do this for a living, supplying printers with bulk quantities, or special commissions.
