it is such a conversation starter :)
I used one of those lighters that have like a plastic picture on them that can be peeled so that i can easily cut and reglue my project to any other lighter when this one is empty :) Be careful to use a special glue that is only for rhinestones, cuz the other ones melt the plastic.
For the second side i printed out two images cuz i was too lazy to photoshop the cross on the cosmic picture.I just cut the cross and glue it to the cosmic picture. Than i cut a piece of clear vinyl tape and taped it to the picture and than to the lighter. I glued some glitter stars on the cross.
