I have this thing. For pretty much every baby that has been born into the family, I have made a blankie and some kind of garment for them to wear. It's just something I do. I only have one kid I didn't make something for and, in my defense, that was because the year leading up to him showing up in the world was really rough. I didn't get much, if any, crafting done that year. I am not thrilled with the colors of this baby yarn but I know it will be soft against a newborn's skin, which is why I'm using it.
The stroller blankie, however, I am going to go stash diving and make up something with vivid colors in a granny square. They don't know the sex of the baby. It's going to be a surprise. So, I'm trying for gender neutral colored stuff.
Here's a pic of the hat in progress. I started it about 10 minutes ago. I'm using sport weight yarn with an H hook.
