I found this random belt I saved from a blanket purchase. The blanket was rolled and the roll had a custom strap on it like it was meant for travel. Two full 32 inch belts with buckles that were attached to each other by a cross section. Both belts wrapped around the blanket and buckled separately. For Bard's quiver you need one belt without the buckle prong and a second belt without any holes but with an additional metal ring at the end.
While taking my custom blanket belt apart, one buckle broke and that forced me to put on an end ring that was more like Bard's anyway. I found an old violin case and took the two carry strap rings and placed them on mine.
Remember the below started out as two identical 32 inch belts with holes and buckles.
A is 32 inches but B has been cut back to 19 (21 before folding the end back over the metal ring).
At the green arrow, I punched a few more holes to match Bard's.
One red arrow points to the strap that came with that belt but the other points to the strap taken from the longer belt because Bard's has two on that end.
At the blue arrow, I opened the ring with pliers to place it through the old buckle loop (the one that broke off) and then closed it by squeezing with pliers.
At the yellow arrow, I cut the belt at 21 inches and folded it back over to form the loop to hold the other end ring. This shortened it to the expected 19 inches with no adjustment holes showing.
The purple arrow is pointing to the buckle that I am calling "good enough" and is the correct color. The two metal rings will need to be bronzed to match it.
Both belts will be painted reddish brown with a light pattern of diagonals as the original shows near the adjustable holes end.
Both mount strap points still need to be cut and riveted in place. The ring ends go on these before riveting is completed.

jessamygriffin 's final quiver pic from her build here on the rpf. This pic is an excellent view of the needed strap contact points where the metal rings loop on.
This also shows the shoulder pad portion that I currently do not have completed.
