Just a little imagination goes a long way
Here are a few of beanies that I made for boys in my family. I have not written a pattern for these, but if you would like one, please let me know and I will try to create one for you.
The first one I call Primary Color Beanie. It is very basic and done in double crochet and has thirteen rows. Between each row of color I used each color together and crochet both at same time then changed to the next color.
The second one I call Spike of Color Beanie. I just tried to break up the black after creating the crown potion of the beanie and this was the result. I then wanted a little color by adding the red and finishing it off with black again. Total of 13 rows in double crochet.
This third one was improvised as well. I used double strand method and a rectangle type pattern.
Total of thirteen rows.
