In this video sewing tutorial I share eight tips on how to hem knits on a regular sewing machine, going through everything from how to keep the fabric from stretching out and getting wobbly to how to sew curved hems and avoid skipped stitches. Some suggestions might sound a bit crazy, but they all work, and often times I find a combination of several tricks and hacks will produce the best result when hemming stretchy knits on a sewing machine. Apart from the eight suggestions in the video, I can’t stress enough the importance of making samples before you start hemming your knit garment. And once you found the perfect settings and tools for this particular fabric, write them down and keep for future reference. The knit samples used in the video are a super stretchy rayon/lycra jersey and a very dense poly/lycra activewear fabric.

Notions for hemming knits mentioned in the video
Needles for knits
I use Schmetz ball point needles and twin needles (Amazon affiliate links) and like them a lot. I’m sure there are many other brands that are great too, but this is the best brand that is available in Sweden.
Clear elastic for stabilizing curved hems
Use a clear elastic that is thin (not the bra strap variety) but still has a some stability and doesn’t break easily. Some clear elastic is so flimsy and delicate which makes it impossible to work with.
Any good quality, thin fusible that has great one-way stretch will work. Do not use the thicker stretch knitted fusible for hemming, it will make the fabric too bulky.
Best option is a thinner water soluble stabilizer or tear-away. But tissue paper works well too, just a bit fiddly to tear away. Whatever material you use it’s important that it is thin, so that there will be no gaping in the stitches
Now sewing knits on a regular sewing machine is a big topic, and if you are interested I could do a similar video on how to sew the side seams on stretchy knits in the future. Also, if you are getting into sewing knits and want to learn more, here comes four book recommendations:
The best book on sewing knits
This is the bible in my humble opinion. Each page is packed to the max with information and I could talk all day about the content of this book, because it is so extensive, but to name a few: The book has very thorough guides on neckline finishes, instructions on how to make swimwear, tips on hemming various material, sewing novelty fabrics such as stretch velvet and chenille and helpful techniques on how to attach zippers to knit fabrics. A little bit dated and lacks info on activewear and stretch lace, but apart from that it is excellent.
A good book on sewing knits
Another solid book on how to sew with knits, including many useful tips and some interesting projects too. The focus of this book is more on the assembly side and understanding how to do various techniques on knits, which means that it is a little less technical than Sewing with knits by Conny Long. What I love the most about this book is that Nancy does a fantastic job explaining techniques and she clearly knows her stuff.
A beginner’s book on sewing knits
This book does a good job explaining the basics and how use the most common sewing techniques. There is also a chapter devoted to fitting knit patterns. This book would be a great choice for a beginner, but someone who already has some experience and is looking for more in depth info on knits might be disappointed. There are some areas which are more extensive than a normal beginner book, such has how to cut the fabric. But for the most part, this book is more of an introduction to knits rather than a bible. Nothing wrong with that, and if you love an attractive layout and less text dense pages, this is also a great choice.
