This post is oldie but still goodie, I made it in Delft, Netherlands some years ago (2016).
My long cardigan is self-made from woolen blend jersey. It is a pattern from 1992 Burda which I altered by lenghtening it and also took away the collar. Rounded patch pockets has a lining inside them and pockets are big enough to create an eyecatching element in the front but also super comfy to keep your hands in. My back bag is made from old leather pants and decorated with studs.
I bought 8 rolls of Ambiente black wool/alpaca yarn (not cheap) and crocheted the scarf with 15 sized hook (made from bamboo). Reason why I spent so much for the materials were that I wanted a black basic scarf with quality material; alpaca mixed with virgin wool makes the scarf super soft and quite light to wear. The extra that makes the scarf pop are the tassels I made from the same yarn. Susanoo remark: the yarn was bought in Delft from a nice, small yarn shop by the canal called Knotten.
Fall/winter is the time of the year when you can daringly play with your outfits- layering different materials and shapes takes the whole look into new dimensions. Why not layer a long cardigan with a short leather vest and experiment freely by mixing scarfs together with different sizes and colors.
