Hi,

Bifilar windings are easy.   Instead of winding one piece of wire around the
core for n turns you wind two wires around the core for n turns.  Keep it nice
and neat and it looks like one long piece of wire but has two connections at one
end of the winding and two at the other end of the winding.  This makes for more
efficient coupling than once winding put on top of the second winding.
