When using your Sew Cool™ Studio make sure you are following these tips for joining fabric.
If your fabric is still jamming in the machine, do not pull or force it out. This could break the needles. Turn the manual knob to raise the needles and gently work the fabric out.
To avoid jamming, change the batteries to make sure your Sew Cool™ Studio is getting enough power and check the needles to ensure they are not damaged.
