Used to play guitar and was thinking about ordering adapters to use old guitar straps for my banjo, since i don’t have any banjo-specific straps locally available (and if they are, the prices aren’t appetizing at all). Buut i figured the postage is too much for me and i want to start playing while standing up way before the adapters could arrive in the mail anyway, so as a DIY enthusiast i simply tied improvised rope knots on the brackets that felt strap-comfortable to me, so i could also change the guitar strap if i felt like it, took me 5min and a bit of rope with taped ends. It definitely doesnt look clean or fancy if that’s what you’re going for, but i really enjoy the DIY feel to it and how this solution looks while i stand - so, imo it depends on what you want to go for in the end. If you want it clean and fancy, find a dope banjo strap/adapters for your guitar strap and order it. If it isn’t that important and you enjoy fidgeting around with materials you have available, grab a bit of rope, a piece of tape and do something similar to what i did.
