When sourcing this material, you must evaluate the base mesh quality, typically made of polyester or nylon, ensuring it has the tensile strength to support the weight of the stones. The rhinestones themselves should be categorized by grade (e.g., AAA or AAAA) and material (glass vs. resin); glass offers superior refractive indices and brilliance. Additionally, verify the fixation method, whether it is Hot-Fix (heat-activated glue) or sewn-on, as this determines the fabric's suitability for different manufacturing processes.
