Kris, nice work:
Here is what I did with mine:
PVC 3 sections, Center 6' 5" wide, sides 2' deep, height 3' 10"
4 10' pvc 1/2 inch $7.00
Walmart $1.00 yard black fabric heavy $8.00
PVC glue $3.00
PVC t's and corners $15.00
Sides fold in with material still on.
Made material like a pillow case to slip on off. (large pillow case)
Less that $40.00
1/2 hr to cut PVC and put together
(1) wife needed for sewing
Less than 5# and is fold-able
