I've used Alpaca, BFL, merino, silk, silk waste and some nylon that Zed sent me. The top was a bit to wonky for me so i've turned it in and blanket stitched it down, i've also created a seam at the bottom that i'm hoping will wear down, i guess i used to much fibre at the edge ?
I'm still very happy anyway and looking forward to starting another and improving as i go !!!
