My very first board was double-sided. I’m using Pulsar’s product. It
wasn’t perfect, but I’m very happy with it. I used 2-sided copper
clad, fully etched the first side with shelf paper on the other side,
and then drilled out a couple of holes for components on opposite
corners. Then I prepared the 2nd piece of transfer paper and poked a
pin through the appropriate places and used the pin to line up the
paper on the board. I applied contact paper to the first side and
etched again. It really came out very, very well.
