When my kids were little I used something to stabilize the rip on the wrong side of the jean fabric then did FME - Free Motion Embroidery - over the rip. My son had lots of footballs, soccer balls and such. My daughter had flowers and other girly designs I made up.
Now, by the time my stuff needs repair it is too worn for even Goodwill. Though they do put them in their rag bin.
