Common questions

Will the spikes survive on a blazer all night?

Yes if you glue them the night before and let the glue cure. Same-day glue peels when the jacket moves.

How do you make the party hat stay on?

Tape a bobby pin to the inside of the hat and clip it to the hair. Elastic straps slip; a bobby pin holds.
