This Instructable will show you how to shorten your skinny jeans without sewing! Also you can wear them normal length after wards too no cutting involved! It just happens that my skinny jeans are colored but this should work for other styles too.
Step 1: FOLD Don't ROLL
The first thing you need to do, is put on your skinny jeans (they have to be on to do this). Then grab the bottom of your skinny jeans a pull up, do not roll them up just pull up when your done they should look like this:
Step 2: Now to Make It Look Sewed...
This is where it gets a little tricky, you fold down to cover the inside out looking part. First you grab the rim of the folded up skinny jean and then you slowly bring it down to over lap the inside out part. I know that sounds confusing but maybe this will help, here's a picture of what it should look like half way down:
Step 3: Line the Seams Up...
Now you should have something like this, but notice how you can tell that you just folded it up, because of the seams being all screwy. Now what you want to do is shift the rim of the folded skinny jean to line up it's seam line with the other unfolded part of the skinny jean seam line.
