I believe I originally found this page through a @MARIANOLEONCZIK rec, but visible mending sounds like it may be up your alley! Especially for those weird pieces. The act of visible mending kinda adds a new sliver of art to your collection, while elongating the lifespan of your piece. barring of course the acceptance that you want your repairs visible. the page I tagged is a good example of this practice in motion!
If you’re looking to add invisible repairs to your pieces, check your local library, secondhand craft store, community center, etc. for classes. In my town, we have a tool library where they teach the average joe how to DIY. keywords would be: leatherwork, embroidery, tailoring, sewing, hemming
