6 wraps on a 3mm ID should get you around .3 per coil. And I'll even throw in a super easy quick start guide for the wire wizard.
*Coil Setup in the top left is self explanatory.
*Wire Builder -
At base line all you need to get resistance is the cores. Claptons and fusings don't contribute to the resistance in any tangible way. Set up as a parallel build. Input your alloys, wire type (round/ribbon) and gauges to the right. For ribbon stacks input the size as a stack: 6 pieces of .4 ribbon should read like .6x.4.
*Results -
For starters the 2 big numbers will be Resistance and Length for a single coil. For dual coil you'll divide the res. in 1/2 and double the length The length will tell you how long your stick should be prior to wrapping. This helps you not waste wire. Though, I always make about an inch or so more just in case.

That's all you need to get started. As you delve deeper to building there are other useful tools in there. But for now that will get you going.
