Pin the hem in place at the top and bottom. Insert one pin first along the top of your hem. Since we folded and ironed the ½ inch in step 2, you should be able easily feel the edge of the fabric from the outside of the pants. Make sure the fabric is straight before you insert your second pin at the bottom. You do not need to do this to both legs. Take another look in the mirror to see if it still looks right.
Now we will measure and pin the other leg.
