I made one last spring. April I think...
Total coat was about $30 and it is still holding together really well. Probably will have to make a new one by spring next year though.
I had priced out the nets and was going to make one myself, but didn't want to shell out $50 to $75 for something I wasn't sure would work.
So I made the one I pictured in this thread on the premise of a "trial" net, and it is still holding up well. Much better then I thought it would. making a slow feeder
