Things you will need:
• Jeans with the broken zip
• stitch remover/seam ripper
• Sewing needle if you don’t have a machine
• Sewing machine best option
• New zip
• Glasses (in my case) lol
You need to start with the right size zip here’s how to measure
Removing the Broken Zip
The first thing you should do is unpick the stitching of the original zip – it is best to start at the waist band just at the top of the zip do this by using your stitch remover/seam ripper and scissors.Don’t unpick the entire waist band just the bit at the top of the zip so you have enough room to stitch the new zip back in later.
Now with the zip completely removed let’s start the tricky bit (I have highlighted where you have removed stitches from) so this is what you should have to start with.
Replacing the broken zip
With the zip foot on your machine. Unfold the flap of the zip and with your zip face down sew on the right side not forgetting to back-tack.
Opposite side now you have 2 pieces of fabric plus the zip to contend with so you’re best to use pins here. Tuck the zip up into the waist band then place fabric back on top now pin the 3 layers together continue down to zip make shore you keep all 3 layers level.
Change the foot back you can now sew the waist band back up that side finished.You’re going to top stitch the zip flap down now, to start tuck the under fabric to one side making shore you don’t sew it in at this point. Starting from the point you can see in the photo simply sew round to the top.
Tuck back into the waist band and top stitch; don’t forget to back-tack.
This is where you’re going to sew now. Has you can see in this photo you have to be careful of the metal that stops the zip, what I do is turn the needle by hand slowly so you can feel your way with the needle.
Right then last thing to do is finish off the top stitching on the zip flap.Now then how easy was that? Give yourself a pat on the back well done you! Any probs just email me I will do my best to help you out
