If you've ever felt this way, then I have the perfect solution for you using this easy peasy hemming tutorial. It literally takes like 10 minutes to do. This is the easiest way to hem your pants keeping the original hem.
What you'll need for this tutorial is:
What you will need to do first is try on the pair of jeans/pants and fold the pant leg up to the desired size that you would need it to be at (as seen below) and then bring it up about 1/2'' more.
Next go ahead and pin it to hold it in place.
Now sew right below the original hem (see below)
What you do next is cut right below the new hem line. This will help to remove all of the excess fabric. Try to cut as close to it as possible.
Voila...just like new!
