Well, my shop is up and running, and there are Things To Buy. That's the good news. The not-exactly-bad-but-not-good-either news is that I do not have anything for the Challenge yet.
I'm working on something that I will count as next week, as I really only spent about an hour on it this week.
Also, tomorrow I get to take some money and go shopping for proper supplies and such. These do not count against the "Only use your stash" rule, because it is things like tools and displays, not crafting bits themselves. Mum will be very happy if I buy my own pliers and dikes.
So stay tuned. Hopefully there will be something of note by next week!
