Portable Walking Foot Dual Feed Upholstery Fabric Sewing Machines, All Metal for up to 1/4" Canvas, Vinyl and Leather Materials |
Portable walking foot sewing machines are made with thread clearances underneath for upholstery threadd. Regular home sewing machines have thread clearances for home sewing machine threads. That is why home sewing machines are restricted to under size 20 needles, and portable walking foot machines can go up to size 25 to accommodate the thicker upholstery threads in the larger needle eyes.
