Total Wash Out........

Rained out for the second year in a row on Pinhole Day.....And my First try of the Solargram seems to have failed.......

Any suggestions from Solargram Experts out there as to what's going on here?

UPDATE:  I've cut away the paper around the Pinhole, thinking that it might have caused the lines as the paper expended when it got wet.........

I'll put it back out for a two week test and see what happens......
