I've used the Stag Cliffhanger Stamp, Gee So Good White Gesso, Gee So Good Black Gesso, Kroma Crackle, Slap It On and an IB Bauble.
Start by painting your bauble with the black gesso. It's so good you will only need one coat. If you need to speed up the drying process you can use a heat gun.
If when it's dry it isn't white enough all you need to do is paint over it with a little more gesso.
When your bauble is completely dry you will need to paint over the crackled section with Slap It On. If you don't do this the crackles will start to peel off.
