What is the ratio of elastic to fabric?
When sewing elastic, a 1:2 or 1:3 elastic sewing ratio is commonly used. Mark four equal distances on the fabric and the elastic with a marker or pin, stretch the elastic to match the markings on the fabric as you sew zigzag stitch.
How do you keep gathers in place?
Use clear tape on heavy duty fabrics
Instead, work two lines of gather stitches within the seam allowance, then draw the fabric up as desired, distributing the gathers evenly. Use fabric clips to hold your ruffles in place, then use clear tape on the wrong side of the fabric to hold everything in position.
Which stitch is used to gathered fabric?
Now, a quick and easy way to make a gather is to use a wide zigzag stitch with a sewing machine. Both the upper and lower thread are pulled long and placed in front of the sewing machine. Then zigzagging is carefully sewed over top of the two threads without catching the threads as it is sewn.
