DIY Ballet Barre
For you intrepid DIY'ers: Ballerinas By Night has some nice instructions on how to make your own ballet barre from standard galvanized pipe.
I made one of these for my home and I love it. Note that most hardware stores carry the pre-threaded, standard-length galvanized pipe sections and fittings you will need for this project. The pipe comes in 1-1/4" diameter or 2" diameter: I used the 1-1/4" pipe for mine, because it was cheaper and lighter-weight. If you want a really solid barre with more heft, and don't mind the extra cost, use the 2" pipe.
I added one hack: I found some rubber stoppers at Lowe's, that I screwed into the "foot" fittings to keep them from scratching my floor.
Good luck with your DIY!
