How to Change Seam Allowance on a Serger

Ask a Sewing Expert Banner


I am a new owner/user of a serger. I want to entirely use a serger to make my next project, specifically learning to sew and cut off fabric using the 1/2″ seam. Is there an easy way for me to edit the instructions so they are 100% serger friendly? Or maybe the serger instructions are available somewhere else?

If you’ve never used a serger before they can be intimidating. From the multiple thread spools on the top, to loopers instead of a bobbin on the bottom, there’s much about a serger that differs from a conventional sewing machine. For you, the only real change you would need to make is to the seam allowance, given that the pattern incorporates a standard 5/8″ seam allowance. I believe you can adjust the seam allowance on the serger to whatever seam allowance you want to use- meaning your pattern can be used as is.

Hope this helps,

    I am rather disappointed in what you have to offer in your video’s. I wanted to learn how to do a ruffled hem on a knit with my serger. All I could find were videos, CDs or books to purchase. That is not the reason I joined the National Sewing Circle. I will not bother to join and would appreciate it if you would cancel my membership. I found several great video’s on Youtube and the two shirts for my granddaughters are completed. Thank you.

    I don’t know anything about fabrics. Why is it that my pillowcase (made of stretch satin) suddenly has really tiny strands/ fibres sticking up at the seams? I’ve read that it’s safe to pop it in the washing machine so what is causing this? Also. Should I continue making my pillowcases out of stretch satin? Or what type of satin should I use that’s equally glossy, cost effective and will not give me this problem after some time ?

    I have a Husqvarna serger That’s about 20 years old which I basically never really used
    It came with a video which I don’t even have a DVR machine anymore. I’m rested now and have started making masks with my Viking rose machine. I need help regarding this serger. Thanks. Carol

    Hello, I do not know how to sew. For Christmas I started with making 4 kuspuks 😳 the hoods blew my mind! Question for another time.
    But I’m excited to learn and want to sew!
    I especially want to learn how to ( for starters alter) my preemie grandsons clothes. He’s going on 4 and his 18 month pants fall off his tiny body, but he’s tall so they’re also extremely short. Issues 1. Elastic, they’re all so different some have so many stitches, some I can’t just sew down the side. So many things in my head. I really want to lean how to make him pants that fit. I know this is a lot but if you have videos or answers I’d be the best student!
    Thank you
