I too want to make a ship in a bottle, but my design is far too epic so it will definately take a long long while, so I decided to practice first before actually trying to make my ship in a bottle, I started by first putting a deck of cards in a bottle soon I'm gonna try putting something else in a bottle I just got some new tweezers.
By the way for the deck of cards in a bottle I got a snapple bottle, drank it, took of wrapper, cleaned bottle, got deck of cards, carefully took cellophane off, put cellophane in bottle carefully, rolled card box carefully, put in bottle in the cellophone. Roll each card and put in one by one, close up and done.
