I have been wanting to do something to cover the holes in my son's jeans. Fist I thought about buying those iron on patches (but they look goofy to me). My next idea was buying duck cloth and somehow sew it on the outside out the jeans covering the whole knee area. I figured duck cloth would hold up better for outside playing clothes. Then I saw this on C.R.A.F.T. I did mine a little differently, but it's the same idea.
I really like how this turned out.
Here he is sporting his now fixed jeans.
First, I opened up the side seams, but not all the way down to the hem. I didn't want to hem them back up (too lazy).
Then turn the jeans right side out and put a scrap of jean fabric behind the holes. Pin in place. Then I sewed back and forth and all around the hole(s).
