My jeans-mending method comes to the rescue again! I did a tutorial ages ago for how I mend holes in jeans to give them an "I meant to do this" look like the trendy pre-worn jeans sometimes have, but also with a super EASY technique that keeps the patching in place as you sew.
I've used this technique a mazillion times, to be exact, and the latest iteration is particularly successful. My friend gave me an old pair of Sevens that didn't fit her and had holes in the knees, and she bought them in a lot on eBay anyway. Oh, if my 15-year-old self could see me now... I FINALLY own a real pair of Sevens!! My fave designer from those days. Still good jeans. Anyway, these were the classic bootcut style, so I did two major things to them: I made them skinnier, so now they're a straight cut, kind of like boyfriend jeans but a little tighter everywhere. Of course, I also mended the holes.
Plenty of detail on that for you... also check out the follow-up tutorial I did on how to mend jeans when the holes are in the knees or other hard-to-maneuver places. It can be done!! Using my same 'ol fave method.
DURING! Turning the jeans inside out...
Applying the fusible interfacing...
In this case, had to reinforce with some cotton on a particularly thinly threaded hole...
MADE SKINNIER.... no pics, oops!
Totally gets that casual boyfriend look, right?! These are like my new fave jeans!! I've been wearing them around partially mended, but now they're done and I can share pics. Love these!
I totally encourage you to take care of your fave jeans and make them wearable for even longer! That ripped look is in and it's quite convenient for those of us who don't like to buy new stuff all the time. ;)
