Embossing tips:
Hold the heat gun steady about 2-3" away when embossing and move along the image as it "takes"
If you wave the gun around it has a tendency to take a bit longer and can blow the powder off.
Exceptions to the above!!
If you are embossing on acetate, foil card, or using clear embossing powder, hold the heat gun 5-6" away or it will
a) buckle your acetate - good acetate can be pulled back into shape if you act quickly
b) lift the foil off the card - very difficult to get it to lay back on!
c) blow the clear embossing powder off, the granules are slightly coarser than normal powders
I you don't have a heat gun, you can use the top of a toaster or the back of an iron (no steam though!) if you are careful.
