Made this for my sons 5th Birthday. He’s having a Lego Themed Birthday so I though it would be fun to make a Lego Head hat for him. Since it’s chilly and I know he’d wear it a lot I made it with bulky yarn and tight stitches. Plus if you choose to make a more detailed lego face you have a good base to sew it on. I only had time to do one size and I made it to fit him specifically. Maybe soon I’ll have more sizes for the base hat. I can tell you if your good at sizing you can still work the 1st few rows (1-4) the same and increase to size need from there. I tried a Nb-3 month to be sure and it’s good. I hope you enjoy it!
