Janome describes its Lap-Seam Foot as an aid for making durable lap seams on medium-heavy to heavyweight fabric without ironing. Its product page lists two width variants: part 202463007 for 9mm machines and part 202503000 for 5mm and 7mm machines. Match the variant to the machine’s maximum stitch-width class; the parts have separate model lists.

Verify the exact setup#

Janome’s page does not say whether either displayed list is exhaustive. A model missing from this page should not be treated as confirmed incompatible; check the current listing or ask Janome or an authorized dealer about the exact model and market. The page also gives no sewing procedure, stitch setting, fabric-thickness ceiling, installation method, or needle-clearance instruction.

Before buying, compare the full model and suffix, maximum stitch width, and part number with current regional documentation. Before sewing, follow the machine and foot manuals and check needle clearance by hand with the machine off wherever they direct. For broader model, attachment, and clearance checks, see the presser-foot compatibility checklist.
