After I posted my tutorial on machine rolled hems, I was asked about sizes of hemming feet. This photo shows some of the feet from my collection. From the left, they are: a straight-stitch hemmer and four various zigzag or shell hemmers (don’t feel bad, I’ve never been able to tell a difference between the two). Personally, I think the straight-stitch hemmer is not really necessary – I’ve actually never used it. The narrower zigzag hemmers are handy for very fine fabrics such as silk chiffon *but* this is not my preferred method so, again, I rarely use these hemmers. The ones that I actually use the most are the two on the far right. The narrower one is great for making shell and lettuce hems on fine knits and lingerie and the wider one is perfect for napkins and shirts. If I had to choose just one, I’d choose the wider one as I think it’s the most useful all around.
