Their size can also vary greatly, so you can use them in a ton of ways. You can use them for the center of flowers, as eyes, for polka dots, and even as lines if you're feeling patient. :D I use them more often while dotting i's in text.
To pull off a french knot successfully, you'll need to follow these steps:
- pull the floss through to the front of the fabric.
- wrap the floss that's between the fabric and the needle around the needle 1, 2, or 3 times. (One time is a small knot, 2 is medium, 3 is large.)
- hold the floss tightly so that it is wrapped around the needle.
- with your other hand, push the needle through to the back of the fabric very close to where the floss emerged.
- keep holding the floss taut and pull the needle all the way through.
- practice this a few hundred times until it becomes second nature. :D
You'll knot these on the back as normal. For the cleanest work, tie off between each french knot. Otherwise, the back of your work will look like that last photo, which is a bad thing if you're using light colored fabric!
I've included two sets of photos for maximum learnin' - the first set is a small french knot, and the second is a medium sized french knot.
