For a small coil, AWG8 solid wire will work just fine.  Fool with that at
first.  The additional losses from using wire instead of tubing are fairly
small, and you might as well get through all the other "teething pains"

Cardboard works quite nicely as a primary support.  Just cut slits, and
shove the wire into it.

Use a toroid, not a sphere...
A pie plate works nicely as a center for the toroid, and then use some of
that metal expandable dryer duct to wrap around.  Or, you can get styrofoam
"wreath base" at a craft store and cover it with aluminum tape.
