I recently did another gradient after my first and forgot to post about it, oops!
I used 2 coats of Leighton Denny's Baby Doll, then sponged on China Glaze's White On White.
It wasn't the best fade ever. I really need to invest in some sponges rather than sponge tip applicators. They seem to work for a bit then give up.
Sorry for the quick post, more soon!
