What is a 1/4 seam allowance?
The 1/4″ seam allowance (it’s not uncommon to see it abbreviated in quilt patterns as SA) is standard for all types of quilting. It’s big enough to hold the patches together. Small enough to reduce bulk and save fabric. Sewing an accurate, reliable 1/4″ seam is the first step to enjoyable quilting.
What is 1/4 seam allowance CM?
For international suitability purposes, use 3/8″ (1 cm) or 5/8″ (1.5 cm) as seam allowances. 1/4″ translates well too, to 0.5 cm. They’re not exact (1/4″ is actually 6 mm), but they’re close enough to be usable.
How do you mark fabric seam allowance?
A common way to note the seam allowance on a sewing pattern without using a physical line, is to add notches along each corner of the pattern pieces. These notches imply the location of each seamline (stitch-line), and are transferred onto fabric once the pattern pieces have been cut.
What are the measurements on a sewing plate?
If you look at the throat plate of your sewing machine, you’ll notice guidelines. Each line is labeled with a measurement: 3/8”, 4/8” (or ½”), 5/8” (industry standard) and 6/8” (or ¾”). A ¼” seam is not labeled because it’s right in line with the edge of your throat plate, closest to the needle.
