There are several different groups starting at different times. So if you miss out on something in the first group, you can try again in another group.
For example, here is a piece in the first group that I liked and it has already sold.
Fantastical Garden by Gillian Moss
The piece that I donated is going to be for auction at the International Quilt Festival in Houston. You can view it online (look at one of the small lines at the beginning of the page) but you have to be there in person to bid on it.
