I used old guitar strings and it worked well

amazing and absolutely beautiful!!!!!!!!!!!!!!!!!!!!!!!!!! I will attach a photo when I finish assembling this! Edit: so I’ve been assembling it and have had the most trouble putting the wheel assembly together because the shafts on the wheels don’t fit into the holes on the wheel assembly even after hours sanding one wheel it wouldn’t fit Edit No.2: I solved the wheel problem surprisingly easily by just breaking the axles off of the wheel and gluing the wheel where it is supposed to go, the rest of the build was fairly straightforward and easy and ended up really good
