Two ideas since I hate things that breaks for no good reason: I bought a "used" (actually just preowned, not used) but real sewing machine for about $50 last year . Even simpler I also figured out that especially for jeans fabric glue is amazingly simple to get right (IMO, YMMW) and if I apply it before damage is done nobody even notices, just make sure you use another washed out fabric, apply fabric glue evenly and apply it to the inside of the knees etc. Edit: removed unnecessary details
