Side netting solutions - DIY vs pre-made?

Just had my first mishit go sideways and dent the drywall. Time to add side netting lol.

Options I'm seeing:

1. Buy pre-made side net panels (~$150-200 each side)
2. Buy netting by the roll and DIY ($50-75 total)
3. Full enclosure kit with sides included (~$800+)

For those who went DIY, what netting did you use and how did you attach it? I don't need it to be pretty, just functional.

My enclosure is 10x10x8 if that helps with recommendations.
