LINKABLESTM - MOSAIC BACKERS
Each LinkableTM mosaic backer is hooked to another. Each hangs below (or above) another. Make the chain as long as you like. The backers are clear acrylic and great for glass on acrylic (GOA) mosaics and make really unique modern art. The standard product includes 3 LinkableTM panels and the option to add 3 more to them. They are available in 5 sizes. They are drilled and include all necessary hooks and a chain for hanging. All are waterproof.
