And Now Comes The Hard Part

All the Psychedelic Squares have been knitted. And now it's time to weave in the ends. Let me tell you, if I can't be a shining example of what you should do, at least let me be a horrible warning. Each of these squares has 16 ends to weave in.

Sixteen! And there are 80 squares. How am I supposed to accomplish that? (Without violence, I mean.)

I'm just going to tell you right now. Weave in the ends as you go, people. Listen to me. I've lived this nightmare.
