I hear this question a lot from my sewing students. Beginning sewers are nervous about their ability to sew along the line without small bobbles. They’re worried that any imperfections will ruin their sewing project. I’m going to tell you the same thing I tell them.
Do your seams have to be perfect? No. Ninety degree jogs in and out probably won’t look right, but a slight wavering here and there usually isn’t a problem. If you’re making something that’s skin-tight kind of fitted, it matters a lot more than if you’re making something loose fitting or flowy.
Since the first project I have my sewing students make is a bean bag or pillow, I tell them to play around with it. PURPOSELY mess up a seam and see how it looks on the finished project. I suggest you try it too. You don’t have to make a beanbag, use a piece of scrap material that’s the same fabric as you’ll be using for your finished project. Pull the seam really tight – you’ll be able to see exactly how any imperfections in the seam line will appear. Most of the time, it’s not noticeable.
A few exceptions: skin tight clothing, spandex or other elastic materials, seams sewn in a contrasting color that are seen on the outside of your completed work. In each of these cases, the seams are quite noticeable. Take your time with them.
Don’t forget, if you sew a seam and discover you’re not happy with it, you can always rip it out. I know it’s not ideal, but one of the things I love about sewing is there’s nothing that’s not correctable. For me, it takes away some of the stress.
If fear of not having perfect seams has been holding you back from starting a sewing project, or learning to sew at all, set that fear aside and give it a try! You’ll be glad you did.
