We've made some rockets out of cereal boxes and inserts from alfoil and cling wrap, along with paint and alfoil. I've just used the cheap coles alfoil for craft.
We're making a Spring mural and one of the things from the EYLF sites I use had a craft idea where you paint the flower stem then use the bottom of a softdrink bottle dipped in paint then stamped on to make the flower.
We've cut out some felt shapes and made a life cycle poster using brightly coloured felt, which you can get cheap in a pack from Crazy Clarks. They might need help with some of the drawings, and young children of course need to be supervised in this.
We've also done glitter art. Using a bottle of PVA glue, gently squeeze to release a small stream that you can draw pictures with, my daughter does stars and love hearts, then sprinkle glitter onto the glue and shake off the excess. Lie it flat to avoid any running of the glue and distortion of the picture.
An old favourite is the drawings where you colour a sheet of A4 cardboard with different colour crayons, then cover with black crayon and scratch out a picture using a toothpick or chopstick or similar.
Just a couple of ideas, hope I haven't taken over your thread in a bad way
