Absolutely! I've made a few wool caps over the years.Can make one made of merino wool?
Can you send some photos of samples? Merino wool as at least 90% of the entire cap with ear flaps too?Absolutely! I've made a few wool caps over the years.
I'd just have to factor the additional fabric cost into the overall price.
Basically just a slight addition of material at the ear to go down. Not flaps as such, I still want to be able to push that material above my hear on warmer days. Notice how the back of the cap slopes down a bit too.
