These two slipper styles are actually the same pattern but showcase one side of the work or the other. They are easily made with the same basic knitting stitches and if you can make one style, you can make the other! The pattern is for slippers from a men's size 6 to 13 and for a women's 6 to 13. I've also provided direct links in the pattern to videos demonstrating the knitting stitches required if you need a little help.
This pattern gives the instructions specifically for both styles as the stitches change slightly from one style to the other. You will need to know how to pick up stitches and knit on double pointed needles to make the cuff. That may sound intimidating, but really isn't very difficult. Knitting on double pointed needles is the same as regular knitting needles but you don't need to flip your knitting over as you are working around in a circle. If you're not sure of how to pick up stitches, I have videos demonstrating this technique and many of the other stitches required on my website.
