Machine basting should be sewn next to the area you are going to final sew unless it is just temporarily holding fabric together such as when you are sewing in a zipper.
How to machine baste
- Set the stitch length on your sewing machine to a long stitch.
- Pin the fabric together as if you were going to sew it.
- Do not backstitch as it would just be harder to remove the basting.
- Bobbin thread can be used in the bobbin and upper thread if the thread is apt to leave marks in or on the fabric.
