Repurposing a sweater deemed "ugly" by my girls, gotten from a thrift store for about $1
The bottom/foot part is cut from the body of the sweater, and the arms of the sweater furnish the leg parts for the socks.
My blanket stitch needs work, however, they're cozy regardless!
See this tutorial for instructions on how to make your own.
Since I had more sweater left over after making the socks, I utilized this tutorial for instructions on making mittens.
The socks should be made a bit smaller than the instructions indicated.
Should have made the mittens a bit bigger than the instructions indicated.
A tighter woven sweater will be sturdier for using the blanket stitch.
You can sew the edges with a stabilizing stitch on your sewing machine.
Decorative hand-stitching could be added.
