We made Patriotic bunting using potato prints and paper triangles strung up (I did this as an activity at the childminding group that I facilitate). I simply cut triangles from white paper, let the children print with red, blue and white paint, then when dried, threaded them with wool and pinned them up.
We had Union Jack skewers for snack time.... made with cocktail sticks filled with strawberries, blueberries and marshmellows.
And played with red and blue sparkly play dough!
My lovely mum gave the girls a keepsake mug of Wills and Kate as she considers it part of the girl's heritage!!!
