¿How do you plan to integrate those springs with the bonnet strap? It would be interesting to know, I'm totally obtuse with handy work...
I’m still cutting my pattern out and I’ll post a few photos in the coming days but I’m making quite a wide bonnet strap and having a leather bit that goes behind the spring attached to one end and unattached to the other end so the spring will be allowed to expand when the strap is tightened
