Winding my own inductor-resistance
If you know the diameter of the core and the inductor is close-wound on it, then the length per turn is $$ Lt = \pi \times (D +d),\ $$ where:

\$ Lt\$ is the length of the turn,

\$ \pi \$ is about 3.14,

\$ D \$ is the diameter of the core, and 

\$ d \$ is the diameter of the wire.

The length of the wire used to wind the core will then be:

$$ Lw = n \times Lt $$

where \$ n \$ is the number of turns,

and the resistance of the winding will be the resistance of the wire per unit length times the length of the wire in the coil.

Generally, though, you'd be primarily concerned with the resistance of the coil in terms of its effect on the Q of the coil, and you'd measure out the length of the wire needed to wind the coil, regardless of its resistance, plus a little extra, just in case.
