Scant 1/4" Seams and How It Can Affect Your Piecing!

A scant 1/4” seam... what is that and how is it different from your regular 1/4” seam? Learn below how to use a scant 1/4” seam and why it will lead to the most accurate piecing!

WHAT IS A SCANT 1/4” SEAM?
A scant 1/4” is, as the name implies, a seam that is slightly smaller than a regular 1/4” seam.

WHY IS IT IMPORTANT?
When you sew your seam, the bulk and spacing created by your thread weight and by ironing the fabric over make it so that you’re no longer at a true 1/4” but slightly larger. When doing precise piecing or piecing together lots of pieces, even a microscopically larger seam will add up and throw your piecing off. The scant 1/4” allows for the bulk to finish at a perfect 1/4”!

HOW DO I DO IT?
First, take into account the thread you’re using. A lower weight thread will add to the bulk and let you know that you probably need to adjust things. Likewise a higher weight thread will add less bulk and require adjustment in the other direction.

You can get a measuring tape or a ruler that you can slip under your needle. Slowly lower your needle so that the tip is exactly at the inch mark. Where the 1/4” mark is, place a piece of masking tape or seam guide tape to mark where to place your fabric against.

If you’re using a 1/4” foot, use your ruler to measure where the needle comes down and use your needle position button to move the needle where it needs to be.

Believe us or not, a scant 1/4" can make a huge difference when you sew! Give it a try next time you piece! Happy sewing!
