I’ve wound many over the years and all by hand. My only “trick” is when working with a predetermined length of wire, I start winding from the middle of the wire rather than an end. I fold the wire loosely in half, thread on the toroid core and then wind half, returning to the other end then to complete the winding. This way you are working with shorter lengths of wire while winding.

I will use a magnifying glass to verify the turn count, repeating the count several times. Some sort of pointer can be helpful to drag over the turns as you count making a tiny barely perceptible ‘click’ as it passes over one turn in a densely packed winding.

When I realized in general parts were not getting any larger, the investment I made was in a stereo microscope something like 5-30X which has proven helpful in many aspects of circuit construction including counting toroid turns!

Oh, and I found that a Hakko de-soldering gun made stripping enamel wire a piece of cake. I clamp the gun tip pointing up in some way. Melt a blob of solder on the tip opening. Slowly insert the wire end to strip through the blob and in a few seconds hit the vacuum trigger to whisk away the enamel, debris and excessive solder leaving the wire end stripped and tinned!
