FAQ
What is 7ss in millimeters?
7ss rhinestones measure approximately 2.1mm to 2.3mm.
What color is Crystal in rhinestones?
Crystal is clear and completely colorless with no coating, delivering pure, bright sparkle. It is the most versatile rhinestone color because it works with every fabric, palette, and design style without introducing any competing hue.
What is the difference between hotfix and non-hotfix (flatback) rhinestones?
Flatback rhinestones have no adhesive on the back; you set them with a fabric or craft glue and a pickup tool. Hotfix rhinestones have a heat-activated adhesive already applied, set with an iron or a BeJeweler® applicator. Flatback is the better choice for delicate or heat-sensitive materials, non-fabric surfaces, and pieces where you want precise, controlled placement.
What glue should I use for flatback rhinestones?
Gem-Tac works well for most fabrics, and E6000 is a strong option for trickier materials like synthetic suede and velvet. Always test on a scrap first to check adhesion and dry time.
