Merry Christmas !
I really like that you've used rocks without painting them first. Their natural colours and patterns have so much more character than a uniform white base. I don't know if the ink is waterproof, but I like the idea of dipping them in water or even having them sitting in a bowl of water to bring out their natural patterns 😀
Thank you, Merry Christmas to you too! 😊
I think the colours are waterproof, I haven't used them for such a long time so I forgot... hmm, I think they are, I will try it later 😉 thank you for the idea
