I LOVED this jacket so much that I made two right in a row! Simplicity 0306.
I used wool fabric for both of the jackets. It was my first time using and wearing 100% wool and I have become a HUGE HUGE fan. These jackets are so warm but lightweight enough that when it warms up I don't die of heat exhaustion. I was very surprised to see mixed reviews for this jacket because I love it so very much. It is just so stinkin comfy!
I will say that I used fleece fabric for my muslin and had some problems with the curves. I think the wool is more pliable so it worked so much better.
