This podcast closes the 2016 year, with details on my Spinzilla 2016 spinning.  Since one of the fibers I spun during that was dyed with natural dyes and the mordants tin and alum, I did a bit of research on those mordants.  I end this podcast with that discussion.  These are links to some of the things mentioned in the podcast. The original dye day for the columbia roving was Episode 52. The Jacob roving I spun was from the Ross Family Farm in Pa. One good blog post I referenced in the natural dye mordant discussion was written by Alpenglow yarns. A second post I read and referenced is by Cheryl Kolander of Aurora Silk.
