A beanie for my younger son who was in need of a hat for the colder days of fall. Very easy to make, all in double crochets in the back loop. I used yarn that I have previously used (some 6 years ago) to make him a sweater. It was a green sweater with beige stripes. Now that I think of it, I could have taken a picture of this sweater. But I did not think about it. I started to unravel it in April 2014 when I was in need of green yarn to make leaves. I do not remember what kind of yarn it is, but it definitely has some wool in it.
If you wish to make the same beanie, you can find the pattern here, made by Drops Design.
