Patching corderoy worn out by friction

[u/lix64]

Hi folks,

I'm pre-emptively patching the crotch and inner thigh of some cotton corderoy trousers where the nap has worn off. I have thick thighs and used to wear these trousers for a job where I walked a lot - so this area has seen a lot of wear.

From here I have two questions:

1) Should I use a patch on the same fabric (I have off cuts from taking up the hem)? It'll blend well, but the patch will inevitably wear down itself (I was thinking of placing the fabric on top). Or, should I opt for a medium weight cotton and try to match the colours.

2) Should I attach the patch and sew repeated lines, back and forth to secure it + help it blend in (like you would denim), or simply sew around the edges? The fabric is relatively thin (they're fashion trousers, rather than rugged work wear) and I don't want to add too much bulk.

Really appreciate everyone's input!

Patch on the inside, it will be much less visible and won’t be as bulky, plus you don’t have to tuck the edges under, just leave them raw and stitch as close to the edge as possible. I always cut a piece that’s too big, stitch where I want, then trim the excess off, use pinking shears if you have them. Stitch around the edge, then lots of stitches in the same direction as the wale, just like you would with denim. Use as close to matching color fabric as possible - it might be too bulky to use the hem fabric, depends on how thick the corduroy is.
