What a fantastic project! I live in the UK now, but my family were early settlers in New Zealand and came from the Highlands (Sutherlands!). I wonder if that's something you could put online elsewhere too, with a donation/pay button? I am a trainer and include sessions on mindful art and play in some of my groups and actually give out some colouring sheets a bit like this...it would be nice to be able to use/donate to a good cause! Best of luck!
