When I'm sewing everything seems fine but when I turn my project right-side-out, and it's stretched a little... you can see the stitches (and it looks awful, to be honest.)
How do I stop this from happening? :|

I made this two months ago at most, but since I just joined... I had to post it anyway!
I had a pair of jeans I got on sale and they weren't really the best quality and had ended up ripping over the pockets. I cut the pockets out and continued wearing them, but then the rips got too big, as in too far across, getting close to the zipper. I didn't want to waste them, so on a day off of school I got the idea to use some leftover fabric, a too small belt, and those jeans to make a purse!
The only problem is that the bottom isn't even, but I might fix it [I should, I'm just lazy. ]
