Dumb question
When I was young my mom and I sat at her sewing machine and she showed me how to sew. She taught me that when I start and end to do the little forward and backward to lock the stitches. I just bought a new machine and it does call out a "lock stitch" My confusion comes from when I watch those quilting/sewing shows and videos. I have never seen them do reverse to lock the stitches. Many times they actually sew big strips and cut them..... so my question is: Do I need be concerned about forward and backward to lock the ends?
