Home for Winterfest
The older couple who enters holding hands looks tired, worried and hopeful all at once. The man speaks up first. “Hello, I’m Thor DeWinter, and this is my wife, Neva. We’re not used to asking for help, but in this case, I’m afraid we have to,” he says.
“Of course. How can I help?”
He glances at Neva, who squeezes his hand and nods encouragingly.
“We just got custody of our six grandchildren when their parents died unexpectedly.”

“The challenge for December is to use this blueprint to design a bakery. You do not need to have the “Get To Work” pack to participate. Your build can be on any size lot and any style you choose. There is no budget but please do not use any custom content. As an added challenge for this month, you can choose to decorate your Bakery for Winterfest and the holiday season if you wish. Hashtag with #BB26 and #aljay2000 when you upload it to the gallery. As always, if you wish to make a household to run your bakery, please feel free to do that as well!”
