Oh, I wish you could feel these! This stitch gives these airy soft little booties/slippers a wonderful 'spongy' feel. I wear a pair of the adult ones and they are soooo comfy!! Best of all, they can be made in one continuous piece from toe to heel and cuff worked right on from there:) Once you get the toe started, these work up incredibly fast! 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!
