The amounts you will need will depend on the number of lanterns, their size and brightness you want, you might need to test a bit to get your desired effect. Be sure that little or no heat is generated by the ones you use and with all 'candles' do no leave unattended. First, pull at the cotton batting until it looks fluffy, light, and cloud-like. Second, hot glue it to the outside of the paper lantern in various places. Make sure it's fluffed to your liking. Third, light the candles and stick them inside. Fourth, hang the lantern wherever you'd like. Now you have your own cloud lantern to hang anywhere in your house.
