Download pattern below in this post.
Sorry this was so long in the posting. My children who help me do some of this had finals and reports to do at school and that took president but it is here now and please enjoy. The collar as it prints from your computer will work as a baby to toddler size yoke or you can use it as a child to preteen collar. If you want it to fit an adult blow it up to the measurements on the sides of the print outs then it will be adult size.
Use size 10 thread for the crochet cord and size 20 thread preferred for filling but you can use size 10 if that is all you can find.
There are two parts to this pattern a left side and a right side make sure you download both pieces to make the collar.
