Well, better late than never...
Here is the sling I sent to Bibbs 2 weeks ago :
.
It took me a lot of time but I was learning the 4 strand braid over a core
I took a polypropylene string, fold in 2 not in the middle (one end finish slightly after the pouch), whipped the loop and braided over this core. I had to add some strands to have 2*4 strands for making the 2 strands pouch.
Since I never managed to use this kind of "pouches", I don't know if he will be able to... But when I tried it, it sure sounded nice with a loud CRACK... and a snow ball in the wall behind me ^^
I took the liberty to post it here now since Bibbs didn't show around since october
