I asked the same question some weeks ago here:

Toroid windings for EFHW

Hello all, i recently purchased a DIY EFHW kit by HB9ZHK: Having never built a 1:49 transformer by myself before I wonder if there is any difference between winding 2:14 or 3:21 turns on the toroid. I found different winding methods which should all be leading to the same result: [toroid_table] [toroid_2_14] [toroid_3_21] [toroid_k6ark] So, which method should I go for? Can I expect any difference between 2:14 and 3:21? Thanks for your replies. 73 Martin, OE5REO

The suggested video by Colin MM0OPX was very interesting and helpful:
