Beautiful
but it'll shrink and felt into a woolly brick if you're not careful about washing it
Been there, done that, makes a great seat pad
Don't thermal shock it (from cold into hot, or vice versa, water) and if you do wash it bring it slowly up to temperature and don't agitate it much. Soaking it in water with a very little detergent (shampoo will do) or plain soap, will remove any finishing, and rinse really well, before you dye it.
That is if you do want to dye it ?
If you raise the temperature of a reaction by 10degC you cut the time of the reaction in half.....kind of bad description of the science, but the reality is that if you leave it soak longer in cool water the blanket will clean just as well as if you'd done it hot in twenty minutes
Overnight, or through the day, in the bath will work fine.
If you want to dye it, you could have a word with Spandit
His tea dye is turning out rather well
Basically you need an acid dye for wool, and if you buy a commercial one and it doesn't say, clearly, on the packet that it will dye wool, then it won't.
Interesting to see what you make of it too
I had one of those Bulawayo blankets; really thick and warm, it's now part of the bedroll for a medieval knight
