I am self taught so be kind in your comments.
This is how I hem jeans that are too long and still maintain that "factory hem" look
I'll be making these 34x30 from 34x32 jeans.
Step 1: Measuring and Pinning
Fold up and measure half the amount you plan to shorten the pants. For me I'm hemming up 2" so I fold the pants up 1" (not including the original hem). Pin it so it don't move. You can also iron and pin.
