What do the TV Show Mad Men and The Naughty Secretary Club book have in common? Well truthfully I am not sure since I have never seen the show. What I do know is that one of the characters Joan looks like she has been flipping through the pages of the book to get some accessory ideas. A friend sent me an email asking if I had noticed the pen necklace that Joan often wears on Mad Men and I quickly did a little googling and found exactly what they were talking about. I adore her necklace and have made several though the years that I have sold on Naughty Secretary Club. Now with the book I have instructions on how to make your own version using a vintage pen cap or a vintage bullet pencil. Just check out the pictures below to get an idea. Grab yourself a copy of the book for full instructions. Not to mention if you don’t want to wear your pen as a necklace there is also a project to wear your pen as a pin!
