Stamp-bossing: Embossing with Stamps!

In this demo-focused virtual workshop participants will learn to make the required tools needed for the technique of stamp embossing. Four styles of embossing tools will be covered by transforming recycled ‘tool’ steel into 

Participants will witness numerous different backing elements to work on during the process of embossing. Pattern layout will be covered in addition to accurate embossing application on the metal surface using the tools made during the class. Emphasis will also be placed on demonstrating various heat treatments for steel and how to properly temper steel to make a lifelong lasting tool.

Come learn how to add dimensional pattern relief to your metal work!

Matthieu moved from Paris to New-Mexico when he was 19, where for seven years he studied Navajo, Hopi and Zuni jewelry techniques. He was immediately drawn to stamping, making concho belts and bracelets. He then moved to Mali, West-Africa and worked for a few years with the Fulani, Touareg and Bambara jewelers. 

In 1999, Matthieu settled in Montreal Canada and continued his studies by going to a jewelry school and learning a more classical part of the trade. Over the years, Matthieu has returned to Africa regularly.

In 2014, Tim McCreight and Mattheiu Cheminee created the Toolbox Initiative, a non-profit organization that helps jewelers in West Africa through the gifts of donated tools.

“I have been stamping and making stamps since the beginning and have developed a form of stamping design by creating patterns that fill the entire piece of metal. This is called “tessellation”.

Matthieu has written two books,  “Legacy, jewelry techniques of West Africa“  and “The Art of Stamping”, both published at Brynmorgen Press.
