EDIT: Please email me: email@example.com and I will send you a PDF of the pattern for free.
I made this little pilot cap pattern when Davis was small...maybe 7 or 8 months ago. Honestly, it is so very simple. I've been tweaking it and hope to add sizes and make enough to have a stack around the house. I love them because you can use them for wearing indoors. I also love the Scandinavian aesthetic...it's such a protective gesture.
I try to make them out of knit fabrics for their softness, and also thick diaper flannel I have left over from making diapers.To save money, we turn our heat to about 65 degrees by day, and 60 by night. So we have to wear sweaters and socks and the baby gets a pilot cap.
The pattern on the sidebar is free and assumes you are familiar with following a pattern and sewing basic things. I think if you are a beginner it would be a good project with someone teaching you how to sew the curves, and how to pin baste. Davis is a year old and for this one I added length and width on the square sides, took in the top a little, added sashes and a lip for grow room.
