How to lengthen a sewing pattern piece

How to lengthen a sewing pattern piece

A simple step by step guide on how to lengthen a sewing pattern piece to fit your body. Most sewing patterns are drafted for someone around 5'5" so you may need to lengthen your patterns if you are taller than this. If your sewing patterns don't already come with a guide line to lengthen at, you can use this guide as reference to draw your own line!

Step 1

Cut along the shorten/lengthen line on the pattern pieces.

Step 2

Separate the pattern pieces by the desired amount, slide a piece of paper underneath and tape in position. Make sure to line up the grainline and centre front / centre back line. The front/back bodice pieces should be increased by the same amount ensuring the side seams line up. NOTE: As you lower the bottom half on the front bodice piece, this also lowers the bust dart point. You will need to bring the bust dart point back up by the same amount. For example, if you lengthen the pattern by 2.5cm (1”) you will need to move the dart point up by 2.5cm (1”).

Step 3

Redraw the seams in a straight line, trimming any excess paper.
