Making a Multi Size Pattern Bigger or smaller

I'm sure we've all got multi size patterns that don't have the size we want on them. It's a real problem when our size falls over the different size range being sold.

I'm going to show you how to draft other sizes using your multi size pattern.  This isn't grading, that's a highly skilled job.....were going to use the distance between each size that the pattern grader created.


Tools of the trade:

> ruler

> pencil

> french curve or flexible ruler if you have one, but not essential

> paper large enough for each pattern piece

Iron the patterns pieces so they're flat.

This photo shows the steps that need to be taken at each corner of the pattern piece. The pattern needs to be really flat. I used weights to hold mine in place. You can use pins, but not too many.

1. Place the ruler so that it accurately joins the corner of each of the sizes and draw a line continuing onto your paper.


2. On the pattern the distance between each size is usually the same. Measure carefully the space between the corners of 2 of the printed lines, exactly at the corner. This measurement is really important, you might want to write it on your paper near this corner.


3. At the corner measure from the pattern along the line you have drawn. Draw a short line exactly the distance you have written down. Repeat this for each size. I needed to make my pattern 3 sizes bigger.


The following photos show this process at different sections of the pattern. Corners, balance marks etc.

The corner of the pattern has lifted slightly in this photo, but it was flat when I drew the line joining the corners.
Remember to do the same for notches and other balance marks.
For some reason the sleeve of my pattern only needed to be made 2 sizes bigger............... so the next pic only has 2 additional sizes

The marks you've drawn need to be joined together. Use a ruler for straight lines. The curved lines need to be the same shape as the original pattern, so measuring the space between the sizes at regular intervals will help, then join the dots into a smooth curve. Using a french curve or flexible ruler will make this easier.


If you need to make the pattern smaller follow the same instructions, drawing the line onto the original pattern rather than onto new paper.
