This year when we did Operation Christmas Child boxes I thought it would be nice to include some hand knit hats since I have a lot of yarn lying around. Since I was going to be making hats for boys and girls to go with three different age groups, I wanted to make a pattern that would work for anyone.I came up with this Growing Rib Hat (click to find on Ravelry) that has an increasing rib pattern for each size.
I made one for the oldest girl with a white body and blue trim, and the two younger girls got blue hats with white trim. The boys each got black hats, because that is probably the easiest color to give to the boys.
The pattern is written to use just the simple Red Heart yarn you can find at pretty much any store, but you can just as easily substitute any size 4 yarn. For the oldest girl’s hat I actually used a sport weight yarn doubled to get nearly the same gauge.
