Spring is here!

$45 material fee due in class

Friday, June 9th


This workshop teaches great fundamentals for building mosaic substrates using packing foam to add depth & texture. A great way to upcycle packaging materials. Our methods are different and allow us to skip the mesh! Less steps always better for time management and profit if you sell your art. Our image is desert related but can be anything...a tree or abstract with depth... and all is doable with imagination! Project measure approximately 11 x 17". Students are provided with sheets of Styrofoam to create their base.

We are back to bring the Fish/Bird/or Whatever Sculpture! In this fun workshop we will begin with a 12x12 1/2" Wedi board. Then, draw your design...yes come prepared with your image if you can. Then we cut out for a negative space around it, then work with wire, smalti and glass tile to bring your sculpture to life. This is a great class that combines many techniques to learn from.

QUILT DIAMONDS_edited_edited_edited_edited.jpg


Our January session of triangle-making was a HUGE success. Studio 9 is committing to sessions every other month.

Claire Barnett at Seattle Mosaic Arts is putting out a nation-wide call for mosaic artists to participate in creating mosaic triangles that will be "sewn" into a large diamond “quilt” becoming a mural promoting reproductive rights for women.  Here is a description:
"Access to safe abortion care is critical to all of us. Even if you have not personally had an abortion, without a doubt someone close to you has. This beautiful community mosaic project visually demonstrates how abortion is part of all our lives. The concept for the quilt is simple. People mosaic small 4” triangles to represent the impact abortion has in their lives and then these small triangles are pieced together into an ever-growing mural. The colors represent the different ways abortion affects us: Orange (I had an abortion), Yellow (my partner had an abortion), Green (a family member had an abortion) or Blue (a friend had an abortion). Our hope is to transform this local project into a national movement. Once people take time to understand how abortion has directly impacted their lives personally it will be very hard to continue to legislate against abortion access. It takes 128 small triangles to create this 5’x3′ diamond. These ever-growing diamonds will then be “quilted” together to create a stunning, powerful mural that can travel around the country, encouraging more people to contribute their own triangles. Please help us showcase this reality by adding your “color” to this quilt".

We will have bi-monthly sessions. Our next two are as follows (we will add more dates in the future):

Sunday May 7th
Sunday July 9th

Session 1:  1:00 - 2:30
Session 2:   3:00 - 4:30
No cost, but a donation to an organization that supports and promotes women's right to make their own reproductive decisions (without her husband, doctor and a member of congress!) is welcome and encouraged.
This is a very simple project, no mosaic experience necessary.

PLEASE READ if you are interested in attending:

  1.  Email Randi at for sign up or more information.

  2. If you want to bring a friend, family member, etc., please, one email to sign up everyone in your group. If everyone signs up individually, you might not all get in.

  3. Be sure when you sign up to specify which session you want to attend, 1:00 or 3:00. Signups are first come, first serve, .

$20 drop in or $150 for a 10-lab card. Pay in person, cash, check or Venmo.
To sign up, text 510-295-3344.

NOTE: Labs are not classes.  You need to have one beginning mosaic class under your belt, or basic mosaic-making know-how (you know how to cut glass, how to use adhesives, etc.) We are happy to answer questions, offer advice or refresh your memory on the finer points of cutting glass or what color grout to use, but there will be no  actual teaching.
