Knitted Basque hat with leaf pattern by DROPS 123-35

I made this basque hat for myself. It is made from the mix of two yarns. The first one is a blend of alpaca, wool and acrylic. The second is a very thin thread (25g=250m) of 85% Super Kid Mohair, 15% Polyamide.

My head size is 58 but when I finished the hat I found out that the top part of it is very small and lacking volume. So I had to unravel it, leaving only the edge size 58 and then follow instructions for size 60. Even now I find that the top part could be bigger compared to the original DROPS model. I think using needles #4,5 could do it.
