Apply Base Coat & Colour Coats as normal.
Rhinestones can be applied onto the tacky colour coat or a thin coat of top coat using a cuticle stick or tweezers. (Studs are 3D & need to be embedded in Gel or Acrylic etc)
(Cure before last top coat if you’re using the top coat under the Rhinestones also)
Apply 1-2 coats of top coat over the Rhinestones to seal them in place.
