Tip one:

Tip two:
Match the zip colour whenever possible to fabric colour or if you are using a multi-coloured fabric then pick the most prominent colour.

Tip three:
Before inserting a new zip ensure that it runs smoothly by opening and closely several times.

Tip four:
Try to match the zip used to the material of the garment.  Nylon teeth zip with lightweight fabrics and metal teeth zips with heavy weight fabrics such as jeans.

Tip five:
Ensure the garment fits correctly before fitting your zip.

Tip six:
Neaten and press seams prior to fitting a zip to ensure a good finish to your garment.

Tip seven:
When pinning a zip into place pin from the bottom up whenever possible.

Tip eight:
When sewing on a machine always use a zipper foot to get close to the teeth for a neat look.

Tip nine:
Line up the top of the zip tape with the top of the fabric, this will allow you to add waistbands, facings or a hook and eye etc later. 

Tip ten:
When sewing the zip in position start at the top and sew down on both sides, this will avoid pulling the fabric in different directions.  

Tip eleven:
When working with light fabrics or loose weave fabrics attach some thin iron-on interfacing to the fly sections only before you start to sew for better results.

Tip twelve:
Use small tight tacking stitches to tack your zip in place before sewing on the machine, this will reduce the amount the zip moves during the machine sewing process.

Hopefully by following these tips you’ll be fitting zips that are perfect every-time in almost no time!
