I have to admit, I'm quite hooked. I love the idea of solar dyeing and imagine what you could gift/create where you have even dyed the yarn! Possibilities are endless. And I love that the ingredients are natural (except perhaps the mordant) I've been thinking of other combinations I might try and have bought a larger glass Kilner jar to replace the plastic one after this use as the instructions say it degrades with time. I've been looking at websites too and apparently you can use white vinegar as the mordant. I might try it to see if it works.
Have you tried solar dyeing? What did you use as dye/mordant?
Finally, I previously mentioned that I would be making the Christening cake for my nieces' Christening and promised a pic - so here it is:
Have a great week!
