Use cording for all buttonholes on stretch fabrics. Follow machines’ instructions and use the buttonhole foot with the little tab on the back to hold the string. White kitchen string is fine.
Stretch elastic and waistbands evenly
Test quality of stitches often
Double needle stitches should look like railroad tracks on the right side
Double needle stitches should look like even zigzag stitches on the wrong side
When fabric is stretched, the stitches should not break, feel tight or pop out
Recheck tension often
Always stitch a straight topstitch line. Do not follow a crooked facing or hem
When serging use a 5/8” seam allowance
When edging use a ¼” seam allowance
A set in sleeve with a cap requires slowly lifting the presser foot to ease the curve of sleeve head into the armhole. Sew slowly
When serging two pieces of fabric together it is important to know they are being fed evenly under the presser foot. After sewing the first few inches, go to the bottom edge and check they are even.
Never topstitch to the very end of a topstitch seam. End one or two stitches away to stop the fabric from being pulled out of shape.
