I have noticed all kinds of tutorials for these little DIY Glitter Snowglobes this year!  Here is a fantastic one from 
Camille Styles:
 There is something amazing about those little magically worlds with fake
 snow in them, and it's even more fun collecting them from different 
locations that I visit. I've never made one, but I need to. Check out 
this one spotted at 
Camile Styles,
 and I think you'll really love that it's filled with glitter. I've got a
 few little characters to make one, so I'm going to get on the stick in 
the next few days. If you want to make one too, visit the post 
here.
