Now that I have a lovely period yellow leather dye that I can use, my next project (maybe over the holidays) is to experiment in figuring out a blue dye. Since our Canton colours are yellow and blue, they'll be important colours for me to figure out.
I have what looks to be a fairly easy recipe for a blue dye, but its a bit odd. Most of the other recipes that use indigo call for lye to be used. That's even the case with fabric dyes and more modern web resources I've found.
I'd prefer to avoid using lye, at least during the winter when I can't go outside or in the garage to have better ventilation.
This recipe doesn't use anything like that, it basically just has indigo, water and gum arabic. That makes me sceptical, but I figure its worth a try.
I know I can get gum arabic at Michaels, and I've ordered some powdered indigo, which should be arriving this week (I've also ordered some green buckthorn berry powder that I can use to try another yellow recipe - why not since I was placing an order anyway).
If the blue works out OK, I'll probably use the blue and yellow for my stick purse. That way we can test it out at a Canton event and it will be colour coordinated.
