I recommend that you have your kids paint their pine cones in the inside of a box or lid. This way when they sprinkle them with glitter the glitter stays inside the box and not all over your kitchen/dining room. They you cna leave your pine cones to dry in the box and once they are dry you can then shake off the extra glitter. The box/lid is very important!
I left the girls pine cones to sit outside all week so they would be completely dry and I shook the extra glitter off while outside as well.
I definitely recommend having your kids wear aprons, I stopped the girls after I took the picture below because Sam splattered paint all over her shirt.
oh and another tip is that you can leave the paint inside the box/lid in case of spillage or if you have a toddler they don’t know how to “clean” their brush so paint gets everywhere! You cna tell by my pictures below.
They came out beautiful!
