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
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.
