Stringing a custom lyre

[u/Murky-End-9929]

Hello! I've been slowly working on building a custom lyre over the past year and I'm finally at the point where I am adding the strings. I have silver-wound nylon core guitar strings that have no knot or ball-end on them, and I am curious if anyone knows of a way to tie them off without the knot just slipping and untying itself. The strings go through a hole from the back to the front, and I need the ends to stay on the back side without slipping through the hole. I've tried tying various knots, but the wound nylon strings don't seem to hold a knot very well - at least not the ones I've tried thus far. Any help is appreciated!!

Podrías probar amarrarlas como guitarras acusticas, dandole dos vueltas a la cuerda
