Ahhh Althea, as a purveyor of many many trade shows I will tell you to curb your thoughts of it not being successful. You may be amazed by a phone call in the next few weeks telling you they saw your stuff and want to meet with you. Most buyers do not buy at shows, they instead gather a list of those they wish to pursue when it is time to buy. So chin up and see what the wind blows your way. I believe that you were at that show for a reason, you may just have thought it was a different reason that it will actually turn out to be.
Glad you had fun with Lissie Bean and Jen, I can only imagine the amount of cackling that went on at that table. AND... you should get Augie an award or a medal of valour
