COMMON SIGNS OF BAD TENSION ARE:
• Loops – the stitch doesn’t lie flat against the fabric,
but bubbles out.
• Bobbin thread shows through the top of the quilt.
• Top thread shows through on the bottom of the quilt.
• Thread breaking.

SAYS: If you’re using two different
colors of thread for the top and bobbin
then you will most likely be able to see the
contrasting color on the opposite side,
unless you are using a thicker poly-batting.
Try to keep the bobbin and top colors similar
if not the same.
COMMON CAUSES OF BAD TENSION ARE:
• Different weight thread on top or bottom
- Whichever thread is heavier is going to pull harder on the other thread. If the
top thread is heavier, you should loosen the top tension to make it even with the
bottom. If the bobbin thread is heavier, you should tighten the top tension to
make it stronger.
• Batting
- If you use batting in some quilts but not others, or if you change batting type
between quilts, you may need to adjust the tension. To test the tension before
sewing on your quilt, first sew on a piece of scrap fabric with batting and see if
the tension needs to be adjusted.
• Fabric
- Changing fabric type may necessitate tension adjustments. To test the tension
before sewing on your quilt, first sew on scrap fabric to see if there needs to be
tension adjustments.
• Thread not correctly in tension disks
- Always make sure your thread is secure and deep down between the tension
discs and that the machine is threaded correctly. Oftentimes loops and poor
stitches come from having the machine incorrectly threaded.
