2-needle, 4-thread overlock sewing machine MO-1000M. - Model Name: MO-1000M - Brand: JUKI - Number of Spools: 4 - Function: Overlock - Color: White This is a 2-needle, 4-thread overlock machine! What is overlock? It's a process that combines edge finishing and main stitching in one step when sewing two layers of fabric together, regardless of the material's stretch. It's convenient because the work is done in one go! But also, when using highly stretchable materials (jersey, leotards, etc.), the more sewing steps there are, the more the material stretches, which can reduce the quality of the finished product! ☆ Usage Frequency I bought it in September 2022, but I only made one blouse and haven't used it since, so I'm selling it. It's in beautiful condition with no scratches. Essential for an overlock machine: ● Easy and convenient automatic needle threader! Accessories Controller, net, spool caps, presser foot, looper threader Head cover → No stains, some wrinkles. Waste fabric box, instruction manual, instruction DVD I have discarded the outer box, so I will pack it carefully for shipping. Thank you!
