I can’t seem to find a matching yarn for the jumper repair (to be fair the colour, texture and thinness are very specific). I looked to see if there were any embroidery flosses that kind of tone but there were only bundles that didn’t have great matches. So I may either try eBay for a single skein or do a temporary job with doubled thread just to hold the hole together and stop it unraveling larger. This is kind of a favourite jumper.
