I suppose it was inevitable, with my having done a post on arm knitting, that I would do a post on finger knitting. The video above clearly demonstrates how it's done. It's a fun and quirky but limited form of knitting: you can only use as many stitches per row as you have fingers, the gauge will be determined by the circumference of your fingers, and the result is inevitably a loopy chain. The question will then be, what will you do with your loopy chain?
I did some googling to find some good finger-knitting project ideas, and to be honest, I hated almost everything I saw. But as with most craft projects, bad results are usually a failure of execution rather than technique, even when as with in this case, the technique is a limited one. I do quite like the wreath above. You can find instructions for making it on Flax & Twine.
I like this cushion cover idea as well. Design Sponge has instructions for making it.
One blogger crocheted her finger knit chain together to make a rug. [Update: The blog this photo came from no longer exists.]
It's also possible to make a finger knit cowl, as this Etsy seller has done. I'm not a fan of the rope cowl, but that's just my personal preference. They can look quite good given the use of the right yarn and when worn with the right outfit, and they're definitely a trend.
The other use I see for finger knitting is as a kid's craft. It might be a good way to introduce children (or, er, adults for that matter) to the concept of knitting, and at any rate it's easy and a lot of children would enjoy making bracelets or headbands for themselves or (with some adult assistance) a cushion for their beds or whatever else they can come up with. Give them leftover balls of yarn and let them go nuts.
Incidentally, I'm hoping not to find myself ever doing a post on toe knitting, but heaven knows researching and writing for this blog has already led me down some strange Google rabbit holes, so it's best not to tempt fate by making any declarations either way.
