Pebble Mosaic - "Circles of Stone"
(Contact me to schedule.)
9:00 am to 4:00 pm
$125 per person

In this introductory mosaic workshop, you will be using various colors of natural pebble and slate to create your mosaic. Design considerations, including using dark and light values, will be discussed as well as how to tint thinset (a cement like product used to adhere tile) and apply it. Sealing your mosaic will be the last step before your framed mosaic is ready to take home.

See what previous students have created during the workshop. I think you will agree they have done an amazing job.…

Express Yourself - Memories & Discovering Flow
(Contact me to schedule.)
2 days
$250 per person

In this workshop, you will be creating a mosaic using ceramic shards, glass, stone, and items of significance to you. In the process, you will choose materials that speak to you and that you feel relate to the special item(s) you want to have in your mosaic. While this workshop is about playful experimentation, we will be considering design, flow, contrast of materials/colors, lightness and darkness, and personal meaning. No experience is needed. It’s about fun!

Andamento I - "Discover the Language of Mosaic"
(Contact me to schedule.)
1 day
$125 per person (limit 4 participants)

The Andamento I workshop may be one of the most important mosaic workshop you can take. It's great for the beginner and the more experienced mosaicist. Come learn the fundamental language of mosaics. Learn how to "read" andamento and how to use it effectively in your own mosaics. Instead of cutting material to learn andamento, we will be drawing them. It is much quicker and easier.

Andamento II - "Expressing With Andamento"
(Contact me to schedule.)
1 day
$125 per person (limit 4 participants)

In this follow-up workshop, you will apply the lessons learned in Andamento I on an image of your choice. In a way, this is "where the rubber hits the road." We will be working on a plan of action for your next mosaic. Through drawing "flow lines" and selecting shape, size, and material of tesserae, you will be closer to achieving the feeling you want to express. Prerequisite: Andamento I.

Don’t forget, a custom tailored class or workshop can be made to meet your needs. Ideas are welcomed. Let me know what you have in mind so we can schedule the date(s) and time that works for you. Gift certificates are also available.

Thank you. David Chidgey
