VeryPinkKnits always explains things well and shows you exactly what you need to do in order to accomplish something. The Hygge feet cabled booties for adults would be warm and cosy and that's the point isn't it? Knit and nurture. You don't have to do the cables if you feel insecure about it. Knit the pattern in stocking stitch or another stitch you are comfortable with so you understand how you create the booties. Once you have done that you can focus on the cables. Without the cabling the booties will be less bulky and hence not as warm. That might suit you. With the cabling you will have lovely knitted booties for a cold winter's night.
