Trade Show Ideas

I’ve done a number of trade shows. I got a lot of great clients through them. One of the ideas I’ve tried is building a corner wall complete with a partial roof, ceiling and window. I added a lot of things in it that I typically find in homes such as ‘mould’, failed window seal, damaged shingles, etc. But it was a lot of work. Has anyone used any amazing trade show ideas that attracted a lot customers?
