Flower Brooch Donations -- Posy Pins!

A year or so, i fell upon this great tuturial for flower pins by Molly Chicken. After making myself one as a tester, i started making some for just about everyone in my life. I even made versions of it as corsages for my mom and mother-in-law for my special day. I get compliments on them all the time, and the odd request to make a stranger one, or sell them at a fair or local store. Having had that feedback, i thought they would be a good first item for me to share with my workplace. Each year, the agency i work for has a craft fair as a means to make some extra fundraising funds (as well as otherwise celebrate the crafty-ness in us) so i made these 4 as a donation to the cause. Now i just hope that they get bought and people love them as much as i do!

Now, my question to you all is: do you call them pins or brooches? I never know the difference, if there is one at all! Edited to add: the great suggestion by Jodi - Posy Pins!
