Anyone install mirrors to help their child learn to dance?

I’m sure some of you have installed mirrors to help your kids practice dance at home. What are some cheap ways to do it or websites that may not cost an arm and a leg to order some?

We had a huge plastic/plexy mirror on our kids playroom wall when they were little. It was suggested to us from our daughter therapist. My kids would spend hrs in the mirror dancing and making funny faces Amazon has some great options for plastic mirror sheets.

I’ve seen people use those cheap long ones from Walmart.
