This is the start of a CJ for a group on Bumbleberry.
The 'sign in' tags have a little handbag, dress or shoe on each one and a space on the back for the person to record their name and date.
The front of the CJ has a material background. I bought this a long time ago and have never found a use for it until now - and it seemed just right. It's actually much shinier irl than on the picture.
