8x8 LED Grid Manually built for max7219

Does anyone have a tutorial on how to wire up an 8x8 led grid?

Can I have the anodes on one side of the perfboard and the cathodes on the other side of the perfboard?

Pretty much I have a costume with two eyes that each will be 8x8 led grids. The two chips along with resistors and connectors are going to be under the mask and I am going to have 16 wires running to each led underneath the mask.

Is there a flat 8xstranded wire that anyone can let me know where to buy? I would need 4 of them for this
