So I took some old wool sweaters. I did not have any so I went to the thrift store and bought them for a few bucks a piece. Make sure your sweaters are 100% wool or they won't felt.
Next step is to felt the sweaters. This is done by washing the sweaters in hot water. I put them in the washer and washed them in my home made Laundry Soap. I did this for 2 washer cycles. When the sweaters came out they went from men's large and extra large to something that would fit a toddler. The argyle looking sweater did not felt. It said 100% wool on the label so it either wasn't what it said or it had already been pre-shrunk.
I cut off the sleeves and cut them down the seam. Then I cut the front and back apart and laid them flat to dry.
I enlarged a kids mitten pattern to fit my hand. When I laid the pattern on the felted sweater I put the bottom up against the ribbing. This will be flipped up after sewn.
I sewed the mittens together. I sewed the seam down on the ribbing so when it was flipped to the outside the seam would not be noticed. Then I sewed a button on using Persian wool yarn.
These mittens are super warm and thick. I will be able to play with my kids in the snow with these!!! I saved the left over felted wool to use for other crafts. I still have the gold and gray sweater to use.
