It is a popular selling brand of yarn, so many shoppers may be disappointed when they are unable to find it, but Bernat yarn may be scarce on the shelves this winter. The yarn is constructed using a variety of materials, with cotton being the key ingredient. Due to the recent failure of cotton crops nationwide, Bernat will not be able to manufacture nearly the number of skeins that they normally produce this time of the year. During the winter, yarn sales climb. This is probably due to the number of Christmas gifts that are made using yarn. This year, Bernat lovers will have to either choose alternative gifts for their loved ones or craft their gifts using another brand of yarn. Many synthetic brands are available. This cotton crop problem will not affect the makers of those brands. Cotton is not used in their yarn.
