Make Six Explosion Boxes with One New Paper Pad from Michaels

[@isabellamorles9151]

I bought the smaller explosion box Michaels has and have been trying to glue the paper onto it and it seems to get crinkly and wrinkly in places. Any advice on how to clean it up? what glue can i use (i have tried liquid and glue sticks). Also for the hearts I have tried to cut out hearts to glue there but they are folding and wrinkling super bad :( It isn't coming out as nice as I hoped... Any advice would be appreciated
