This embroidery knot is very similar in appearance to a french knot, but I personally think they look a bit smaller and neater than french knots! It takes a bit of practice to get the hang of it, but I personally find colonial knots fun to stitch
Come up through the fabric and take your needle and place it under the thread.
Now take the thread and twist over the tip of the needle, forming a figure 8.
Bring your needle back down through the fabric right next to where you initially came up. Make sure to hold tension on the thread while you’re doing this.
