In my constant search for alternative materials, I came across 2,000 feet of flat braided nylon line on Facebook Marketplace. Besides needing to be lugged (heavy barrel!) I had to wash it before I could use it.
It wove beautifully, but I had to be careful to pull the warp very tight. The weavers were a bit looser. I stuffed it with 1" foam.
I am constantly being asked if porch rockers can stay outside (nooo...that's why they're called PORCH rockers) These should be able to be left outside a bit more, but brought in , in winter.
