There are two ways that you can create custom jewel dots in the exact colors to fit your project. I don’t know about you, but I never seem to have just the right color on hand.
One way is to use your alcohol markers and color them
The second way, if you need quite a few is to use embossing powder. You take the gems and cover them with versamark inks. Then cover that with embossing powder. Use your heat gun to heat the powder and set aside till cool. I get perfect results every time
