not so great

Well, The Vera Project craft bazaar sucked. Actually, the other vendors were great, and the venue was great, but The Vera Project did a really bad job of promoting and advertising the event. In other words, there were almost NO customers - which is ridiculous considering the great venue and vendors and the fact that there were TONS of customers at another craft fair (Urban Craft Uprising) about 200 yards from us. All they had to do what put up big signs pointing people in our direction, but that didn't happen. So I sat with lots of other lonely vendors and knitted.

On the other hand, there were some pluses to this experience...
1. Got a lot of knitting and embroidering done and am, particularly, excited about how this embroidery turned out...

2. Sold a couple of things.
3. Got my name out there and distributed my cards/info.
4. Met some other talented and nice vendors/artists
5. FINALLY weaved in all the freaking ends and tagged most of my projects.

So, with all that prep-work done, I'm hoping to set up a table at the Ballard Farmer's Market on Sunday. However, since the market's policy is that vendors provide their own tents (which I don't have), I'm wondering what kind of chance I should take as a tentless vendor.

Any advice? 10% chance of rain/snow? 30%? 80%?
