Hairspray fixative for chalk pastel projects

Second grade students are bringing home their portfolios today.  Inside the portfolio, there is a pastel landscape.  Pastels are extremely fun, but also extremely messy.  They will never stop being messy unless you spray a fixative on them.

Artist fixatives are expensive and smelly; but fortunately, there is an alternative!  Spray aerosol hairspray 6-8 inches above the artwork and let it dry!  If there is still chalk coming off on your fingers, spray it again.  The hairspray acts like a glue to hold the chalk in place.  If you don't have any of this type of hairspray in the house, you can find it at the dollar store.  I don't recommend pump hairspray because the droplets coming out are much larger and can leave dark spots all over the artwork.  Aerosol creates an even, fine mist that works very well.
