I just snagged a treasury! I've been pretty lucky getting these lately. So this time I decided to feature my Mad Scientist of Etsy team August challenge. The challenge was microbiology. Just search "MSOEteam challenge" on Etsy to find these items (and previous challenge entries)!
I normally don't like including my items in my own treasuries, but since not all of the team members have completed the challenge, I needed to in order to fill it up. A few of the items I chose weren't submitted for the challenge, but fit in the microbiology theme.
