How To Mend A Seam - The Step-By-Step Guide

Equipment Needed to Mend a Seam:

  • Clothing with at least one busted seam
  • Sewing kit
  • Needle
  • Thread
  • Scissors

How to Mend A Seam in 10 simple steps:

  • 1
    First, you need to have a good look at the hem and confirm exactly what needs re-sewing. Turn your item inside out and asses the area. Asses whether your item has been surged. If the surged threads have been damaged you will need to remove them. If not leave them as is. This will save you time and 'why fix it if it's not broken' right.
  • 2
    Always remember when mending always make sure your thread is the dominant color of the item of clothing.
  • 3
    If there are any loose threads around the area you will need to tie them off. You should find a thread at each end, in some cases two. Make sure these are tied off and secure to stop any further unthreading. A good way to do this is by tying the threads at each end together.
  • 4
    Once the threads are tied off you should be left with a nice open hole to mend.
  • 5
    Pin together (or use seam tape) the open gap to make it easier to sew together.
  • 6
    To start your sew insert your needle 1/4 - 1/2 inch behind where your seam has started to come apart. Start off your new sew as close to the existing hem as possible. 
  • 7
    Sew diagonally from the hem down the seam until you reach the start of the opening. Once you get to the opening start to sew down the middle. You can use the original holes as a guide. Follow these holes, but remember to sew above the holes to avoid them showing on the finished piece.
  • 8
    Sew in nice small stitches to ensure that it will be a long-lasting seam.
  • 9
    Sew until you reach the other side of the gap. Then sew diagonally 1/4 - 1/2 inch up the existing seam to the hem. Exactly as you did at the start.
  • 10
    Tie off your thread and snip off 1/8 - 1/4 away from your knot at both ends.

Congratulations you have mended your first hem! 

And there you have it how to mend a seam.
