I use FW acrylic inks. They are archival.

Thank you Les, I shall look into those . Yes Africa really gets under your skin it's a wonderful continent.

Hi Sylvia, have a look at Dr Ph Martins Hydrus Fine Art Watercolour, they are a liquid and so may allow you to use them like your inks. Being archival and light fast you will be able to continue with your lovely vibrant watercolours without further problems. They also do "radiant" watercolours which are stunning but they are not lightfast and will fade I love your sketch books on your gallery by the way, and thanks for your kind comments about my Kilimanjaro picture, yes Africa does get under your skin doesn't it!
