  10. Stitch on right side of fabric, using sense of touch to follow edge
  11. 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.
  12. Stretch elastic and waistbands evenly
  13. Test quality of stitches often
  14. Double needle stitches should look like railroad tracks on the right side
  15. Double needle stitches should look like even zigzag stitches on the wrong side
  16. When fabric is stretched, the stitches should not break, feel tight or pop out
  17. Recheck tension often
  18. Always stitch a straight topstitch line. Do not follow a crooked facing or hem
  19. When serging use a 5/8” seam allowance
  20. When edging use a ¼” seam allowance
  21. 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
  22. 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.
  23. 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.
