First you want to wash your bottles and jars and make sure all labels, residue, and oils have been removed. Give the glass a rinse in rubbing alcohol. Make sure your hands are clean and dry and try to avoid touching the glass so you don’t transfer any body oils to the glass.
Basically all you need to do is draw on your glass with the 3D Writers. I actually touched the glass with the tip of he bottle and “drew” to make spots larger. I drew some squiggly lines on some of them too. Just start with one color, placing dots and larger spots in random places. Repeat with the next color, then the next, etc, until you are happy with the design.
To cover up the threaded rims and make them look prettier, I used the red 3D Writer and just covered the sides and top of the rim completely.
For the long neck on the Balsamic vinegar bottle, I drew a line around the neck going upward. I repeated this with different colors, overlapping occasionally.
Once they have dried for 48 hours, place them into a cold oven. Turn the oven temp to 200 F. Bake for 30 minutes. Turn the oven off, open the door, and allow them to cool inside the oven.
