In my experience, homemade boards are at best temporary. I would bread-board a cross over, tweak it, and find your favorite flavor. If it were me, I would then get some terminal strips like what's in all the kits and screw them down to a chunk of wood and solder all the pieces point-to-point.
The lab I work in has a $15k mill for making circuit boards, and even then they are just made to be prototypes. I would stick to wire and PTP connections.
