I had three different people try these on when I was working out the sizing and every one RAVED about how comfy they are, and they are! This stitch gives these great slippers a wonderful 'spongy' feel. Best of all, they can be made in one continuous piece from toe to heel and cuff worked right on from there:) These have a wonderful amount of stretch, which is a result of the stitch as opposed to the yarn, so almost any type of yarn will produce this same lofty, stretchy results. Pattern includes instructional pictures and is definitely explanatory enough that even a dedicated beginner who has never done the stitches involved could complete these with ease!
