It can be used for many things, but here I show it in the form of a hat finishing.
One that is cute, easy to make and practical:
So I thought of working an i-cord finishing some time ago! And I did make one first interpretation of an i-cord "knot" in one of my hat patterns (the reverse and shift hat you can see on the right). Only later I tried another i-cord construction, where the cord makes a complete turn and is grafted near the start of it, to form a loop...
(I first used this finishing on my Casazul hats, that are seen hanging below)
In the Casazul pattern I had added a photo-tutorial to showcase the construction of the i-cord loop, but I thought that for my newest pattern a video would be in order, to really showcase the construction of this loop in an easy to follow manner, so as to enable everybody to try the tiny little loop out to finish their hats!
(Of course this exact same method can be used for any kind of knitted loop that you might need, in any size and form --- for any project!)
