Large Wooden Mosaic Bases 16 Pack - Assorted Shapes for Coasters

Our review of these Large Wooden Mosaic Bases finds them ideal for crafters who want a ready-to-use substrate for glass-on-glass mosaic coasters and small decor projects. The single biggest reason to buy is convenience: each bamboo base arrives sanded and sealed so there is no prep work, which speeds up setup and lets makers focus on design and tile placement. This pack of 16 assorted shapes gives enough variety and quantity for workshops, classroom activities, or multiple gift projects without hunting for additional blanks.

Key Features

• Great value pack: Sixteen bamboo substrates in assorted shapes provide multiple projects or class supplies in one purchase so you can create sets or try different designs.
• Craft-ready surface: Each base is sanded smooth and sealed so mosaic glass adheres cleanly and there is no need for additional sanding or priming before gluing.
• Varied shapes: Circles, hearts, squares, stars and other shapes expand creative options and let makers match shapes to themes or coaster styles.
• Beginner friendly: Ready-to-use blanks simplify the workflow for novices and reduce prep time so new mosaic artists can focus on learning tile placement and grout techniques.
• Indoor use: Designed for indoor crafts and decor, these wooden bases work well for coasters, wall accents, and classroom art projects where moisture exposure is limited.

Who It's For

This product is best for hobbyists, teachers, craft group leaders, and experienced mosaic artists who want a convenient set of pre-finished wooden substrates to speed up assembly. The variety in one pack suits holiday crafting, classroom projects, or making multiple coaster sets to sell or gift.

Those who need outdoor-ready or waterproof bases should look elsewhere, as these are intended for indoor craft use and are not described as weatherproof. If you require very large panels or specialized mounting hardware, these small coaster-size blanks may not meet that need.
