Here's how I made a felted neck warmer from a wool scarf.
This striped wool scarf used to be so long that I could wrap it around my neck four times with plenty of extra hanging down.
This was one of the items "saved" from our house fire in May. It came back to me from the dry cleaners measuring a paltry 10" wide X 36" long.
Waaahhh! What to do? So, after some thought and brainstorming, I decided to still use it.
Step 1: Fold It, Pin It and Sew It
I folded it over into thirds lengthwise, so that the seam would face my neck.
Then, I pinned the entire seam, so I could hand sew it as straight as possible.
I used a blanket stitch with red thread on the outside of the scarf seam (what would become the "right" side of the scarf). This is the side that will touch my neck and clothes.
Then, I turned it inside out, and blanket stitched it again, to make sure that the project would be nice and strong and maintain its shape.
