Gail asked about how I sew buttonholes on narrow knit bands, so I thought I should share the methods that I use when working with knits. I’m sure there are more ways out there so please chime in in the comment section if you have other tips!
One way stretch interfacing method
This method works very well on jersey, interlock and rib knits. The tricot interfacing I use for this purpose only has one way stretch and I place the interfacing so that it stretches crosswise and subsequently takes away the lengthwise stretch of the fabric, which is good since I will sew vertical buttonholes.
Using elastic thread
This method is great for fabrics that you can’t or don’t want to interface (such as ribbing). You can also use this method in combination with 4-way stretch interfacing.
When all else fails
I am not good at making buttonholes in delicate knits or spongy knits, though Connie Long (Amazon affiliate link) has great pointers on that in her book. Instead I resort to my favorite “cheat” which is using a combination of metal snaps and buttons. Like this:
Yes, it’s not the same thing as proper buttonholes, but I really like this style as it reminds me of vintage garments.
