THREE GRAINS OF SEWING
There are three different grains in a piece of fabric and each one has different properties.
The Lengthwise Grain runs parallel to the selvedge and is the most sturdy and has the least amount of “give” when pulled. These are the threads that are held on the loom and kept taught during the weaving process. This grain is used to keep the garment hanging straight so it doesn’t twist on the body.
The Crosswise Grain runs perpendicular to the selvedge and has some amount of “give” when pulled. These are the threads that are wrapped on the shuttle and passed back and forth on the loom. This grain is placed so that the threads go around the body. Since there is a little “give”, it is more comfortable as the body moves in the garment.
The Bias Grain runs diagonally to the selvedge at a 45 degree angle. It has the most “give” when pulled because the threads are not held in a stable position like the lengthwise or crosswise grain. It can be pressed into curves and is very useful for curved bindings and bias tape. However, sometimes the bias can be a problem.
WHAT IS STAY STITCHING AND WHY DO WE NEED IT
Sewing a pattern involves working with many bias edges. Bias edges stretch with handling, and the process of assembling these pieces can mean lots of handling. We don’t want these edges to stretch because necklines will gape, collars and facings won’t fit and the overall appearance of the garment won’t be pleasing. Stay stitching will prevent this stretching by keeping the fibers in place. The pattern piece will maintain the original size and shape.
Some examples of bias edges that benefit from stay stitching include the neckline, the shoulder seam, waistline, and the armholes. Even princess seams on a bodice have some bias and need stabilization.
Sleeve caps are another bias edge. Here, the bias is controlled with the gathering/ease stitching used to insert the sleeve into the armhole.
HOW TO DO STAY STITCHING
Set your machine to a 3.0 stitch length. If your machine has needle positions, move it one click to the right, putting the stay stitiching just inside the seam allowance.
Always start from the highest point of the seam and stitch down to the lowest. Stitch each piece separately.

BODICE STAY STITCHING
For the neck, start at the shoulder and stitch around to the center front. Stop and flip the neckline over to the other side. This means one half is stitched on the right side and the other half is stitched on the wrong side. Start at the other shoulder and stitch around to the center front, meeting at your previous stitching.
Since shoulder seams slope downwards, start at the neck edge and stitch out to the armscye edge. Flip the fabric as you did for the neck and stitch the other shoulder.
Armscye stay stitching likewise starts at the shoulder and is stitched around to the side seam. Flip the fabric again as you did for the bodice and stitch around the other armhole.
Press the stay stitching gently to press out any little puckers that might result. Just use the tip of the iron along the stitching to make it nice and flat.
SKIRT/PANTS STAY STITCHING
Stay stitch the waist seam from the side (highest point) to the center. I usually skip over the dart areas. If the sides are very flared, stay stitch them from the hem (highest point when the skirt is held horizontal) to the waist.
That’s all there is to it. It’s a simple and effective way to maintain the shape and fit of your pattern pieces.
