Simple but with a nice detail: tubular cast on is very useful for
bottom-up hats, where the cast on is right over our face and a neat edge is what we need!
This pattern is part of a collection of 4 project (Onde Collection), each one to make with a single skein of Malabrigo Worsted.

This is a free pattern. If you want, you can support my work buying the whole Onde Collection (4 patterns).
Enjoy!
