About 40 sequins to add a bunch of extra sparkle to Princess Aerie the Fairy's gown. These sequins are attached with petite seed beads. You only need 37 for the pattern, but the extras are just in case!
 
One day i nthe far future I will run out of these sequins, so if you want to buy way more than you'll ever need here is the shop I bought them from:
