My duct tape rose display at Dickens on the Strand. I didn't sell nearly as many as I did at Onicon, but I wasn't giving my all to my roses either. I was also there as a photographer for the Air Ship Isabella, and I walked in all the parades. So I was not just there for my art. I did make enough off of them to warrant the three days I took off of work, which makes me really happy!
Side note, if you would like to order some roses, I do have plenty left over. No big though, they will eventually get sold, if no one buys them online.
Just thought I'd add that last bit in.
