How to lengthen the wires on the led lights

Hey everyone,
Total noob here with a question about how to add wires to the ones on the led strips, I needed to strip the negative wire on the led light and attached along with the negative power line to my controller, but I constantly couldn’t correctly strip the led wire and kept cutting more and more of this wire that I I ended up might not have long enough wire on the strip to use it.
