Tyson is pretty decent at sewing.
He learnt how to do the basics at school, but he never got much practice until his army days where he began stitching repairs into his clothes and earning rations from other soldiers by doing little patch jobs on their clothes that didn’t need full replacements.
Afterwards, Tyson was the one repairing his and Sebastian’s clothes whilst they were on the run. He also learnt a lot more about stitching skin back together during those days as well.
Now, Tyson largely only spends his time sewing together cosplay for his nephew’s amusement, repairing his dog’s stuffed toys, and - much more commonly - doing medical stitches.
