I searched and I believe the last time there was one of this was in June 2012.
Here's the details of the swap from last one.
Details of swap: Jar of Whimsies Round 11
This is a swap where you will fill a container (glass, plastic, wood, cardboard/paper, metal, fabric, whatever your heart desires) with little trinkets, bits, and baubles you think your partner will love. The more creative the better! Requirements are as follows:
1. A decorated container filled with whimsies
Small- approx. 2 cups (1 pint); OR
Large- approx. 5 cups (2 pints)
2. A minimum of 3 crafted whimsies (more is just fine)
Note: Extras (i.e. things outside the container) are optional- discuss with your partner.
