I have used this Baby Blues Hat by DROPS Design pattern to create a hat for my son.
It is very easy pattern with good instructions to follow. It is very good for beginners and I would say quite quick project too (e.g. I spent a probably an hour a day and took me a week to complete the hat).
I gave it a little twist with a little bit different colour scheme and edging.
Here is the final result:
Let me know, if you like it 🙂
