You can use any stretchy fabric, not just nylons. I used a cotton knit fabric for my watermelons, I had scraps left from a sewing project that were just the right shape. Tie the ends to something sturdy, and nestle the squash (or melon) in the fabric like a sling. Because the fabric I used was white they ended up looking like melon bras, but it works.
(The watermelon I’m growing only gets up to around 3 pounds, I wouldn’t suggest using this technique for the really big melons)
Photos please...
I used pantyhose I bought at the dollar store. I tried to sling a leg under each one, but they kept sliding off. I cut a hole in one, and slid the squash in it. It’s holding so far, but it’s got a run in it.
