It has not been posted and won't be for a while after this one wraps up. Probably a month's break would be good. I just gave the parameters early because some people like to work ahead and have already finished this swap and mailed their blocks in.
No rush... we will finish this swap and rest from our 9-patches for about a month. Then we'll be back at it with scrappy and white! No need to start making those before the sign ups happen.
