Welcome mosaic lover! Glad you’re here.

Our Mosaic Collective a group of mosaic enthusiasts of various levels from amateur beginner to professional, founded by Elina Rosenblum of Blum Arts Mosaic Studio in 2024. We gather to exchange ideas and experience, share our work, support each other in our mosaic projects, and talk all things mosaic. Occasionally, we take classes with visiting mosaic instructors and participate in group mosaic shows. We are open to any mosaic-related events, ideas, or initiatives.

New members are very welcome. If you are a local mosaic artist, we’d love to hear from you!
