Something that really trips up both new sewers and experienced seamstresses alike when starting to sew bras is how to neatly sew the bra back hook and eye closures on neatly. These are some pictures I took for my sewing friend Maddie when she was having difficulty getting the hook portion to not skip when using a zig-zag stitch. She had to resort to using a straight stitch because she was getting results similar to above.
The main problem is the hooks drag against the needle plate more than the eye side causing the machine to just refuse to sew, skip or go crooked but fear not there are two possible ways around this.
In general the problem with sewing the closures on is there is uneven foot pressure because the two sides are not level. By using a gift card as a shim and using the needle in the far right position with the hooks facing up you can get a better result.
Still not absolutely perfect so I switched to a leather roller foot. Unfortunately for domestic machines Bernina is only domestic sewing machine company to make a foot exactly like this. I use this for when I sew my shoe uppers. But it provides a constant feed the same as the feed dogs. But unless you have a Bernina or a high shank machine you’re out of luck on this particular doodad but there are alternatives for low shank machines.
I also use a foot like this for sewing the elastic one. It stops bunching and lumping. The image quality unfortunately isn’t great these were quick iphone pictures I did at the time but you can compare the two methods to the regular way. I think either are fine ways or getting a professional finish if you take a little more care than I did on these.
I sell both the bra back hook and eye closures and hook and eye tape in my Etsy store. I will be listing some more colors and styles soon.
