This is my favourite slipper pattern. It is also easily converted to crochet. It is super easy using garter stitch all the way.
I've knitted, crocheted and sewn many slippers, but this is still my all time favorite pattern that I've made customizable to any yarn you have and any sized foot.
You can wear them cuff up, or folded down. They are super comfortable and warm.
Feel free to download the pattern here.
ENJOY!! Send me pics of your results, I would love to see and share them.
