I love the newsletters I get from Strauch Fiber Equipment.  They always lead me to such wonderful places.  In this case the article points out, in a very quick way, a method of adding in extra materials into a batt, that goes through a drum carder, without getting extra things stuck in the drum carder.  Great article!

Happy Crafting!
