The idea behind the set was simply that evangelism can be breathtakingly exhilarating (and a little bit scary) - kind of like taking a leap off a cliff into the ocean - but it can also as simple as inviting your neighbor over for coffee.

I am pretty sure it wouldn't have taken 24 hours if I'd taken the fabric off the back and painted it, and then glued it back on. But the effect of painting inside the squares actually came off pretty well from a distance, and made it look like the view through a window. I don't think I'll try it that way again, tho - I don't recover from all-niters as well as I once did!
