My husband and I made this completely fabulous DIY playstand for my niece's birthday. It turned out fantastic. Ana's plans were straightforward and easy to follow. The most difficult part was making the buntings, but even those turned out fine. The only recommendations that I have beyond what is in Ana's post are use a good piece of plywood since it isn't easy to sand, and to put the extra velcro for holding back the theater curtains on the back. My cost is a little higher than the one on the original plans, but I also factored in the cost of the different fabrics, velcro, etc.
