I designed this scarf to go with a beautiful hat pattern I found over at wordsnneedles (http://wordsnneedles.com/WN/2014/11/candy-swirl-crochet-h...). It is a one size fits all type of pattern since it’s a scarf and just needs to be made to whatever size and length you are going for. I have noted what the repeats are so it is easy to size. For an adult woman’s scarf and matching hat (mentioned above) I used 1 skein of Red Heart Unforgettable or 3 skeins of Lion Brand Lanscapes (new Aran). The Unforgettable leaves slightly larger holes between shells than the Landscapes.
