Rising Card Invisible Thread Knot

Hey everyone, So, I have some 0.2 elastic invisible thread. I need to make some invisible thread loops for my Rising Card deck; I only have one left, and it could break at any moment. The one I'm currently using is about 6 cm (doubled), so around 12 cm if I were to unknot it. Does anyone know how to tie invisible thread without losing their patience and control? I must be all thumbs or just missing something, but it's impossible for me. I'm opening this thread to get ideas on how to tie it without the knot slipping. Thanks, everyone!
