12 months ago I would have said plug and play and purchase of the shelf. 12 months later and it has been very satisfying to have built and got everything working. Some items were held together by "bandaids" but the viewers didnt know that. It has been a learning curve, but it has been a great one. If you are just starting out ask lots of questions and be prepared to think (amongst other things) lights,music and power all year round. The end result is all that matters. And if you cant get it done this year, get it ready for next year. My planning has already started for 2018 - only 332 days until the show starts again.
