Crayola Crayons to mark fabric!

I usually use tailors chalk to do most of my markings but I don't like that the fabric likes to slip while I'm marking it.  I also use tailor tacks but they take forever.  A friend recommended I use Crayola crayons and I can't believe how well they work!  The best part is they're super cheap and you can get them everywhere!  They also come in an amazing variety of colors - and it's easy to mark white fabric with light yellow.  These crayons are designed for kids so they're incredibly easy to wash off.  I can usually get rid of my marks with a wet cloth.
