How can a decorator be successful with sandcarving?

Start with proper and quality equipment for this process. Purchasing quality equipment comes with quality support. 

Also consider attending a sandcarving workshop. A good workshop gives you the knowledge and experience to handle glass, stone, metal, painting, carving, UV-gluing, and producing photoresist stencils. Experience gives you confidence to handle more projects. Sandcarving is a low investment with great-profit opportunity.
