Okay, I am going to try stoning a dress my self for the first time...yikes :shock: Have a few questions..... 1. Which is the best: flat back, hot fix, or sew on? 2. I know it varies on the design, but approx how many stones do you need for a dress? 3. What is the rule of thumb for size? The bigger, the more sparkle? 4. Any advice?
