Yes! Her friend is the other baker. In fact, I saw a lot of this bride's family, cousins etc with the same last name on the bakery's Facebook page but I guess they still liked my cake. The bride said her mom and she herself were raving about the flavor. Will get the deposit ASAP!
And don't give any sketches or ANYTHING until you do!! She may still try getting your designs and ideas for free and then bring them back to her friend to implement. For your own sake make it a big deposit, especially if she has a habit of not being worried about loosing them!
