Question

a) Tension is too tight
b) Tension is too loose
c) Needles are dull
d) Blades are dull

Answer 1

Jagged edges on fabric when using a serger are most likely due to dull blades. Replacing or sharpening the serger blades should resolve the issue.

Step-by-step explanation:

If the edges of your fabric are jagged when using a serger, the most likely culprit is dull blades. A serger trims the edge of the fabric as it sews, so if the blades are not sharp enough, they may leave a jagged edge rather than a clean cut. Tension issues may cause loops or puckering, and dull needles can lead to skipped stitches or damage to the fabric, but they would not typically result in jagged edges. To resolve this, you would need to replace or sharpen the serger blades.
