So neat - Wedding Food Ideas - Bonfire Night is a UK thing, but these could also be for the of July. Not sure if I can get the chocolate finger biscuits in the US though. Maybe choc covered pretzel sticks would work?
Have your kids make a fireworks craft for the of July using wet chalk and a piece of paper. It's a super easy art project that you can make for memorial day as well. Wet chalk with water for 30 seconds then draw fireworks on black paper.
