Can't wait to try the hair spray technique. I used a roll of duct tape to make a holder for the chalk and a cap. I make it loose enough as I wrap it around the chalk so that I can keep using it as the chalk wears out. The cap fits firmly on the holder, though, to keep the dust from getting everywhere.

Here's how: wrap the chalk with the sticky side up first, then wrap another layer on top of it to cover the adhesive. You may want to put cardboard or a peice of plastic in between the two layers to give it that lasting touch of quality.

While leaving the the holder in place on the chalk, make the cap the same way.  This will enable a snug-fitting cap. 

For ease of carrying, place a strand of baling wire between the 2 layers of duct tape and then make a little hook on the exposed end that will fit over a belt loop or into a piercing if you are a former casino worker turned adjuster.  Functional and fashionable all at the same time. 

 Don't forget the hot glue gun and some faux gems for that extra  " Bling "
