Learn the simple technique to blend two different size patterns into one that fits you!
How to blend two size patterns
Step 1 First, you’ll need to take accurate measurements to determine what sizes you fall between. This free printable body measurement guide will come in handy to help you take accurate measurements.
I always fall between sizes. I am larger in the hips than I am in the shoulders and chest. As you can imagine, this has caused me some trouble purchasing clothing! That is a huge reason why I started this blog! I wanted to share the message with other women, that..it’s not you, it’s them! It isn’t your body, it’s the clothes! Let’s face it, there is no one size fits all!
For this particular exercise, I used Filles á maman , Extraordinary Girl pattern. They are awesome because you have the option to print only one size! Or, in this case, only two sizes! For nearly every home sewing or PDF pattern I’ve used, I need to blend a larger bottom with a smaller top, and this pattern was no exception. I fell between a Small and a Medium size.
Step 2 Using a vary form pattern making ruler (or you can just free hand it!) draw a line to blend the two sizes into one. For me, I need to have the sizes blend right at the waist. I started a few inches below the waistline to get a really nice blend.
Step 3 Now, in order to match our blend on the back panel, measure down from the under arm and record that measurement. For me, it was 7.25″. Now, measure the length of your blend line. Again, record that measurement. Mine was 4.5″.
Step 4 Mark your back panel with the measurements above.
Tip: Alternatively, you can blend sizes on the front panel, cut it out, and then trace the new blend line onto the back panel.
Step 5 Draw in the curve between your markings.
Step 6 You’re finished! Cut out your pattern and get sewing!
Every pattern, situation and body, of course, will be different. For this particular pattern, I was able to blend the larger bottom with the smaller top. I was able to use the small pattern pieces for the sleeve, yoke, and neck bands. The only alteration I had to make was to the front and back body panels.
