“& now because of the steadiness of the Church they began to [be] exceeding rich having Abundance of all things whatsoever they stood in need, Abundancee of Flocks & herds & fatlings of every kind & also abundance of Grain & of gold & of Silver & of precious things & abundance [of] Silk & fine twined linen & all manner of good homely cloth,”

The Handwritten Book of Mormon (West Valley City, UT: Dan Wees, August 2017), 281 (Alma 1:29).

There is no evidence of any Silk production in BOM Era Mesoamerica, let alone an “abundance.”
