In this post, I'll walk you through a couple common adjustments on blending sizes and adjusting the rise of your halfmoon 101 JEANS. When sewing pants or jeans for ourselves, it's common to have to make a fitting adjustments to get the garment to fit our bodies just right. Use the links above for tips on crotch modifications and making adjustments for knock knees or fuller thighs.
BLENDING or GRADING BETWEEN SIZES
If your waist, hip or thigh measurements landed in different sizes you can blend between sizes. Blend your center front (and back) seams smoothly from one size at the waist to another at the hips.
Example - Blending to a larger size at the hips:
Don't forget to make your blending adjustments to both the front and back pattern pieces! You can also blend out to another size at the thighs.
Cut the pattern along the rise lengthen/shorten line.
To lengthen add a piece of tissue or scrap paper, taping to one edge. Measure away from the lengthen/shorten line by the amount of length you wish to add, drawing a parallel line to mark this. Tape the other half of your pattern piece along this line, aligning the side seam of both pieces.
To shorten you would follow this same process but overlap the pieces by the amount you wish to shorten.
Mark the new cut lines by blending smoothly between the changes from your lengthening or shortening.
Trim off the excess scrap paper.
You need to lengthen or shorten the front and back pattern pieces equally, so don’t forget to also adjust your back piece by the same amount. You should also adjust your fly pieces to add or remove the same amount.
