Look at my crotch!
 
Darn!
 
@bubbalumpkis It’s in my genes!
 
Yay! Welcome to an addictive hobby. I have found darning jeans durably quite difficult, combination of stiff fabric and lots of tension as you move. I tore a few beautiful repairs within a day or so. It can help to use some backing fabric, stitch through all the way (eg using a Japanse sashiko pattern), and include a large area around the tear. Let us know how this one holds!
 
@mbjj Huzzah! So far so good. In this case the jeans are the sort that are a bit stretchy, so maybe that will save me. So far I’ve worn them a few days in a row with no noticeable impact, so fingers crossed I got lucky! Glad to be among the ranks of repairers who care(er)!
