Well you know the problems I've had with Durston Peter and you can bet there are no instructions with any of their new products. I haven't looked in a while but still didn't get the dimensions of the 14 stakes in their Planishing set which they have been promising since the beginning of the year.
I usually use a drill to wind my jump rings round as I don't make that many at a time but a metal knitting needle would be good, I have plenty of those too!
