My wife was hammering me for months to build a lemonade stand for our kids. I know selfishly she only wanted it for pictures. She showed me a couple different ones she liked on the internet, and then I decided to design/build my own.
I used Microsoft Visio to draw up the plans and to determine all the materials I would need. I purchased the materials from Home Depot and built the lemonade stand using my Ryobi 18V tools. My wife did all the sanding and painting. I am good at making things and she is good at making things look cute.
