There are several common problems that can occur while using cotton sewing thread, and here are some ways to troubleshoot them:
Thread breakage: Thread breakage is a common problem when sewing with cotton thread. It can be caused by a variety of reasons, such as using a thread that is too thick for the fabric, a dull or damaged needle, incorrect tension, or sewing too fast. To troubleshoot this problem, try the following:
Use a thinner cotton thread that is suitable for the fabric.
Replace the needle with a new, sharp one that is appropriate for the fabric.
Adjust the tension to the correct setting.
Slow down your sewing speed.
Tangled or twisted thread: Another common problem is tangled or twisted thread. This can be caused by a number of factors, such as improper thread placement, incorrect tension, or a dirty or damaged bobbin case. To troubleshoot this problem, try the following:
Re-thread the machine, making sure that the thread is placed correctly and the tension is set properly.
Clean the bobbin case and replace it if necessary.
Make sure the needle is not bent or damaged, as this can cause the thread to twist or tangle.
Uneven or skipped stitches: Uneven or skipped stitches can be caused by several factors, including incorrect tension, a damaged or dull needle, or improper thread placement. To troubleshoot this problem, try the following:
Adjust the tension to the correct setting.
Replace the needle with a new, sharp one that is appropriate for the fabric.
Make sure the thread is placed correctly in the machine and the needle.
Make sure the fabric is properly fed through the machine and is not pulled or pushed too tightly.
Puckering or gathering of fabric: Puckering or gathering of fabric can be caused by incorrect tension, using the wrong needle or thread, or sewing too tightly. To troubleshoot this problem, try the following:
Adjust the tension to the correct setting.
Use the appropriate needle and thread for the fabric.
Sew with a looser stitch length.
Make sure the fabric is properly supported and fed through the machine.
Thread bunching on the underside of the fabric: Thread bunching on the underside of the fabric can be caused by a number of factors, including incorrect bobbin placement, incorrect thread tension, or using the wrong bobbin. To troubleshoot this problem, try the following:
Check that the bobbin is inserted correctly and is the correct type for the machine.
Adjust the thread tension to the correct setting.
Make sure the bobbin case is clean and free of debris.
Make sure the thread is properly threaded through the bobbin case and the machine.
