Journaling in Braille Bibles


Brought to you by Donna Bauermiller

At Denny’s Workshop

Optional (free) Preparation Session: Friday, May 10, 2019, 7-8:30 pm

Cost $40

MUST PREREGISTER as limited spaces available.

Donna Bauermiller makes “the most exquisite, heartfelt journals that leave us speechless” (click here for interview and photos from Portland Art Collective blog).  Donna will teach us how she creates visual journals in Braille Bibles using such mediums as Golden Fluid Acrylics and Holtz Distress Re-inkers.  (Other examples available at

“I love to see my favorite colors glazed onto a page and then I write on top of this.   The process is very meditative for me.  I work slowly… My mind wanders.  It’s kind of like traveling through time and space to me,” shares Bauermiller.

 Supplies needed: Braille Bible (available on internet or Denny can order) prepped with clear gesso.  Prepping may be done in advance at the optional session the night before.  Please talk to Denny for prepping instructions.  You may bring images and quotes, or they will be available at the Workshop.

This is an incredible opportunity to learn from a gifted and thoughtful visual journalist.  Please register and pay in advance as there are a limited number of spaces.

Create a breathtaking glass-on-glass mosaic masterpiece! No experience required! Everything will be provided for you. This is a 2.5 day workshop, with  Kory Dollar of Marvelous Mosaic Fine Art, where you will start with custom framed window, approx 12″x 12″ that will be transformed into a gorgeous work of art.

The mandala mosaic workshop is open to all skill levels, advanced to intermediate.  The focus for this workshop will be on symmetrical balance and color theory related to glass on glass mosaics. Students will design a one-of-a-kind piece of fine art that will be mesmerizing. First, you will select a color pallet from the array of glass that will be available. Second, you will decide how many mandalas will you will be working with and what the unique centers will be. Kory will have an assortment of vintage jewels, bike gears, and other unique items for you to select from. This is also a great time to look for other unique elements to make this piece special to you, like grandmas jewelry. Next, you will will develop confidence in cutting. Once, you have your color pallet selected and you feel comfortable cutting you will intuitively let your mandala evolve, using the abundance of materials available.

This workshop will teach you how to patternize your glass, breaking down each cut from a strip of glass. This process will assist you in understanding how to maximize your glass while getting the cut you are trying to achieve. We will discuss the physics of glass and why it breaks the way it does. I will introduce several online resources you may use when designing your mandala mosaic. These resources are free to use and will assist you in developing a great color pallet and a unique design.  If you have a laptop, please bring it to class.

We will discuss lighting and how it impacts your design and color selection. Kory will introduce her Opacity Rules for Glass on Glass ® and you will become confident in your color selection. You will understand how to produce a visually stunning mosaic with light and without light, the “Night Time View and the Day Time View.”

This class will not only increase your cutting skills and empower your creativity; it will enhance your knowledge of glass on glass mosaics and the elements required to create a  ever-changing quality piece of fine art that will last a lifetime. Kory will share with you her process and give tips and tricks, including introduce you to tools that make learning glass on glass mosaics easy and effortless.

Limited spaces remaining.  Register now!
