Deni! Well, I've had to experiment and I've ended up putting a bigger blob on than I think you're supposed to cos it takes longer than 5 -10 mins to dry. If I put any less on there it shrinks to the tiniest little part of the lens and that's just not enough for me. I try to be consistent and put the same amt on every day and get the clearest results that way. Just try to get a bit of spit without any bubbles in cos they destroy the pattern.

Good luck!
