Step 4: Finish the Pieces
First of all, a lot of the pieces you make are going to look kind of rough. You'll get better with practice, and you can eat the mistakes. Before giving up let the pieces you have made cool, and once they have cooled completely, lift the parchment up and peel it away from the candy (don't try to lift the candy, you'll probably break it.) Flip it over - the back probably looks a lot better than the front.
You can just lay the bad side down on top of a cupcake, but if you want both sides to look good you can glue two pieces 'bad' sides together with a bit more candy. To get them to stand up on cupcakes or something similar just use a butter knife to make a small cut, then push the candy into the cut.
When I was done I put my bottles in the fridge for a while. When they were cold and I squeezed all of the candy broke away from the sides and came out of the bottle. It tasted great sprinkled over ice cream. You could also just leave the bottles in the fridge until your want to make more pieces.
