Yes, using wires as jumpers is good too. I'm amazed in TV sets, stereos,
etc. most all the printed circuit boards are one sided. The problem
I saw was with the actual IC pins. Sockets would make it worse.
If you don't plan ahead, there might be not enough lead to solder
to on the component side of some disk capacitors (resistors mounted
on end?), etc.
