Yea, Its a pretty cool operation. Eric Henry the owner is a really really great guy
Correct on accounts, although I have never met Eric his reputation precedes him. The process can be replicated without the post-dye (and patent infringement!) Waaayyy off topic however beet dye has been around for longer than I'll know without research but a fixer is required for washfastness and a binding agent for printing (it will most likely stink without a post launder) and again off topic for those beet lovers and/or literary enthusiasts to check out "Jitterbug Perfume" by Tom Robbins heres a taste from page one...........
"The beet is the most intense of vegetables. The radish, admittedly, is more feverish, but the fire of the radish is a cold fire. The fire of discontent not of passion. Tomatoes are lusty enough, yet there runs through tomatoes
an undercurrent of frivolity.
Beets are deadly serious.
If you get past that, be ready for quite a journey
