Questions about the indirect method
From what little I understand about the indirect method, it is that you design your pattern upside down and when you flip it, it is flat instead of bumpy.
But do you have to then mosaic into a mold? What if you want a flat surface when you mosaic a glass table?
Can you explain better than I did how the indirect method works? And if it's possible if you have a certain sized surface you are working with and don't have a mold?
