At the beginning of class, Yulia will give a presentation on flower mosaics. She will also do a thorough demo on how to set up a double-reverse project, select a color palette, and draw out andamento. Students will learn how to cut glass into ”brush-stroke” modules that Yulia uses to create her own flower portraits. Yulia will discuss proper use of tools, glass cutting techniques, and how to solve problems. Grouting will not be done during this workshop, however a grouting demo on how to grout and blend multiple colors will be given at the end. Images will be provided by the instructor or students can choose their own upon the instructor’s approval. Most of the supplies will be provided, all students must bring their own glass nipping and cutting tools.

Students will learn how to translate images of flowers into realistic and powerful mosaic statements. In our image choices we will consider composition, gesture, colors, and other aspects of effective portrayal of a flower.  We will concentrate on creating a close-up of a flower, a version of a “portrait” using a double reverse mosaic method. The double reverse technique allows for a photo-realistic depiction of an object, precise color matching and exact shape fitting because the entire layout happens right over an actual image photo. After the layout is finished the work will be safely transferred to a 10″ x 12″ permanent substrate.

The goal of this intermediate session is to help students observe sources of inspiration allowing for the creation of their own signature textural and temporal andamento studies. Students who have some basic mosaic-cutting and fitting experience will boost their know-how by learning to analyze why they are drawn to a particular work of art by examining and “unpacking” the compositions and andamento of a variety of mosaic works. This intense observation will allow them to assess how the andamento is used to create a mood or effect, as well as some basics on composition. Students should bring one printed or emailed example of a work they want to deconstruct as well as images that are inspiring that could serve as a possible mosaic. This class will allow them to see in a new way, and to create texture that will enhance the character of their mosaics by utilizing several methods for creating tactile textures based on both a presentation and hands-on work.

Each student will execute a set of two samples based on four possible options— Shell Out, Rising Up, Pebble Waves, Detritus Assemblage. These dynamic and dimensional samples can be used as a visual reference for future works. The materials provided will be affixed to a cement board substrate with thinset. There will be explanations and instruction provided to the group at large, after which each student will receive individual attention. The last part of the class will be devoted to a group discussion and critique, if requested.
