Our steps are very similar, only I don't turn the item upside down. I have made a bracket (similar to an upside down T) that I can slide my dry erase marker up and down for marking. With a ruler this lets me jot down the height I drew my lines at so when I apply the resist its at the same exact location. I agree with you on the look. I'm looking into using a laser for 'cutting' my resist on some large flat orders I do, but I will still sandblast them. For flutes, bottles, etc. I have a old cylindical engraver with a diamond cutter - to me that this is the quickest way to do flutes/wine glasses. I can have a set done in about the same amount of time it takes the computer to boot up. Cutting with the diamond gives such a nice cut that I'm able to offer many color fill choices.
