For me it was the first time i saw Knot Cups like those! They have a nice curve on the end of the loop and it's easy to make a nice loop whit this curve. Those Knot Cups are different of the other Knot Cups i found on other store those one are Top Quality and solid i really love those Knot Cups they are Perfect! I realy enjoy to worked whit those cute Knot Cups and i appreciated to worked whit Top Quality Finding it change the look of you're Projects so it's worted!!
