Every year when I put them up they always seem to be to curl up on the corners or don't stick evenly. Are there any tips to making them stick better?
Answers:    Be sure the chalice is clean and dry. Then spray the cling beside hairspray. The old fashioned benevolent, Aqua Net, etc. in an aerosol can. Smooth out adjectives bubble and let dry to the cup. Do this on a dry day and the moisture collecting on the windowpane later customarily does not cause them to buckle and slide.
my grandma other wet the porthole just a moment or two tiny bit before sticking them to it. it other seemed to hold them stick better than just a dry fanlight.
