Here is a FREE crochet pattern for one of the cutest cardigan/sweater patterns I have ever come across!
Although this crochet pattern is pretty advanced, it is well worth learning the needed steps to complete this project.
There are many helpful links contained within the pattern to help you on your way with this pattern.
Although DROPS Cotton Viscose yarn is recommended, there is within the pattern also a link that will provide you with information to assist you with choosing a different yarn to use as a substitute.
