Aveen, in regards to the pin traders at the events they can be a pretty unfriendly lot as a whole. we were incredibly lucky to get taken under the wings of two traders from Holland. Wim and Bianca who unfortunately don't go to DLP anymore because Bianca is a die hard Tink fan and finds that she can trade more pins in USA and have two long holidays compared to one in Paris. They introduced us to several people who we now e-mail a lot and try to meet up with when we go on holiday. And there is one man who we call Pin Santa because of his white beard, he has tons of pins. Literally. He is willing to trade with anyone but can be a little eccentric. You can't miss him, he takes up two to three of the long dining tables and lays all of his pins out for you to look through.
Don't let the others, mostly the french, put you off. If you take cards with your pin pics ID on and pass them around you should get a few hits and some enjoyable chats. And there are quite a lot of english traders there. One we met comes from Southampton.
Have never had a refusal from a CM, well apart from a jokey one from Patrick when I saw a stitch pin on his waistcoat and tried to nick it he he.
Happy trading. So jealous that everyone seems to be going to or coming back from Paris.
