When I was pregnant I made several hats for my new little one. Two of those hats were knit from wool because being a Sept. baby, Emily was due for some cold days early on and I wanted to make sure that her cuteness not be diminished by some warm hand knits. However, my pregnancy brain didn't trigger that babies don't like to wear a lot of wool because it can be itchy. This is true for my baby. Two seconds after donning her new hats Emily would imitate our Wednesday Tornado Siren. I quickly decided to line her hats with some nice cotton jersey knit fabric. It was a piece of cake but I wanted to share a quick picture tutorial in case any other babies have moms as forgetful as Emily's.
First lay out your hat on a big piece of paper and trace all around the hat.
Cut out your pattern piece and trace it onto a folded piece of cotton jersey knit fabric. Make sure the stretch is going width wise. Cut out your hat liner- you should have 2 pieces.
With RS together, serge or zig zag stitch around your hat, leaving the bottom open.
Fold up the bottom of the hat 1/2 in. toward the wrong side and stitch around the hem. Insert lining into hat and pin in place. Starting on the back of the hat and using a narrow zig zag stitch begin sewing the lining to the hat. Stitch in between rows if you can to hide the stitches. Since my brim was garter stitch, I was able to stitch between purl bumps to hide my stitches- you can barely see them in the bottom picture. Trim your threads.
Your baby, toddler, or older kid is sure to enjoy their hand knit wool hats much more with a nice smooth lining. I am even considering lining my wool hats for the extra warmth and to prevent itching. I deserve something nice too :)
