Demonstration of the thread exposure to perform the knot simulating letters. A) letter C and B) letter D.
Holding the thread, approximately 3cm away from the needle, with the needle holder, the forceps should be placed on the thread, making a loop with the thread over the forceps for the execution of the first knot. The needle will pass to the other side, being rotated medially, simulating a letter D. Then, repeating the same movement, the second knot is made. Thus, if the exercise was performed with the right hand, a “C D C” is obtained, and if it is performed with the left hand, a “D C D” will be obtained (
