Whole-project checker

Can this machine handle the whole project?

The easy straight run is not the test. Check the thickest seam intersection, the required stitch, the real working room, and how the fabric feeds without stretching or stalling.

Duck's read

Test the thickest real seam

Stitch, full layer stack, needle and thread, working clearance, and feed method all need a yes.

“Heavy duty” is not a fabric chart

Use the manual’s needle, thread, fabric, stitch, and presser-foot guidance. Then sew a test stack that includes hems, elastic, interfacing, and every place where layers pile up.

Primary example: Brother's fabric, thread, and needle guidance shows why the exact combination matters.
