The elves did another fabulous job for me. My order of dying materials from New York came in yesterday, just in time for Christmas. Guess what I'll be doing over the holidays. :)
I'd ordered my powdered gum arabic, along with my ripe buckthorn berries (which are for making a green dye).
Shipping from New York City was about $12, which isn't too bad. And it didn't get held up very much at all at the border. The payment went through on my credit card on the 12th and it had arrived by the 19th.
This is all good news because this is the only supplier I've found that carries the ripe buckthorn berries.
With the gum arabic in hand, I'll also be able to do another attempt at making my blue dye, and see if it works better this time. Fingers crossed.
