Simple and effective, these folding bag holders are great, except in anything more than a light breeze. Here, I was using them to fill large leaf bags with grass mulch. This has been my only use for them so far, and they’re worth it just for that. But they’d come in handy for any sort of collection, including leafy greens harvest. They’re also reversible: stand them on one end or the other for large or regular size bags. These were under $15 at the local hardware store.
