So u cut the top of a bottle off an d put the bit you drink agains on the paper so it was upsidedown an then pour diffrent colour paint into it and then pull it of and then hold each side of the paper and tilt it intil it is coverd if youd didnt fill the paper the first time thats fine just repeat the process until the papers coverd with paint and this is my one, just to warn you half way thrue you might feel like giving up but just do it cause the finished results are good (MESSY)
