Does anyone know a good place to buy a practice beam?
DH actually made one for DD. He used a 4" x 6" x 12' and wrapped it with thin foam and then with vinyl. Pieces of 2 x 4 on the ends for stability and that's it. It's mounted on stair risers so we can control the height as needed and we have an 8" mat for underneath. The whole thing cost less than $50. Here's a pic:
