This part was the trickiest, but this tutorial (found via....Pinterest!....shocking) is the one I used, and it makes it sooo simple! I'm not even going to try to do a better job. Just go there and follow the instructions. I'm not going to lie, it wasn't a piece of cake, but with the tutorial I really think anyone could do it.
So....the end result....
The waistband fits perfectly.
The pockets will never come out again mwa-ha-ha-ha.
They look like mom jeans..........
I'm not loving these now any more than I was before...I really think the main problem is that these jeans were already so old and worn. Also, I can't pull off skinny jeans. They always look the best on skinny mini girls. Third, I don't think these pants could handle all of the changes I made (or maybe I couldn't handle all the changes the pants needed?).
My recommendation--don't do all of these things to one pair of pants!! If it's just one thing to fix I think it will turn out looking a lot better. I would still recommend practicing all of these things with a pair of pants you wouldn't be heartbroken to lose just in case.
Good luck if you try to tackle any of these fixes. I would love to see how you do, and if you have any tips I would love to hear them!
EDIT: I just today found a new way of taking in the waistband that is 1) requires no measuring, 2) is waaay less time consuming, and is 3) such a better idea all around. No, I have not tried it yet, but I'm 100% positive it's better than what I tried!
