Mend a frayed trouser hem with this simple Letsfixit guide.
Cut out a piece of material to be used as backing for the repair. The color does not matter as it will not be seen.
The backing material is placed behind the frayed area. I used Stitch Witchery between patch and frayed area. A hot iron will bond the patch to frayed area.
The hem is recreated just a bit higher than the repair. Be sure to pin.
