Plushy minky is a longer thicker fluffier minky. You can order it as a collar on its own on this page or add  as a lining to another material. 

To order as a lining on another material choose "best match minky"  in the lining drop down  on the order page for the material you would like for the collar and then in the notes for the collar tell me the product ID of the plushy you would like as a lining.
