The LARGE Crystal Ninja Work Mat is a full-size rhinestone workstation printed with everything you need to plan and execute professional crystal projects. The mat features all six foundational fill patterns for rhinestone application, a complete rhinestone size table for quick reference, and the Crystal Ninja branding and rhinestone flower design that makes it as beautiful as it is functional. Spread this mat across your work table and you have instant access to size comparisons, pattern guides, and a protected surface that keeps adhesive off your furniture. The fill pattern guides printed along the edge show you exactly how different stone layouts look, so you can choose the right pattern before you start gluing. This is the mat we use in the CrystalNinja studio and the one we recommend to every RhinestoneArtist.com member. With 18 five-star reviews, rhinestone artists love having their most-used reference charts built right into their workspace. Measurement Disclaimer The printed ruler (inches and centimeters) on this work mat is provided as a convenient reference for general measuring and project layout. Because the ruler is printed on a flexible rubber surface, slight variations can occur during the manufacturing and printing process. Material movement, stretching, shrinking, or the natural weight and flexibility of the rubber may cause the printed measurements to vary slightly from true scale. For this reason, the printed ruler should be used as a general guide only and is not intended for precision measuring. For projects requiring exact measurements, please use a calibrated ruler or measuring tool.
