I wound my first toroid back in 1970's, Just recently I wound two toroids.
Remember, that when you wind them, you take the wire and essentially fold it in half. Wind one half and ten the lother, so you don't have to pull all of the wire through the core. The max is 1/2. Mine was a bifilar, two different wire guages and about 80" long. I wound about 80 turns in about 25 minutes.
If your winding a large core or using finer wires, you can make a tool that can help you wind. This is essentially a flat bar with a small cutout except for the two ends. You wind onto the bar, then pass the bar through the core.
