I am looking for a children’s book I read in the late 70s or early 80s that was about fairies and giants and other mystical creatures. It was huge (to a 6 year old!), 13 to 15 inches in height & hundreds of pages printed on very thin tissue-like paper that was pastel multi-coloured, in sections. A pink section, then a yellow section, then a pale green section, etc. I believe the coloured sections coordinated with the sections of the book which i think were divided into “stories about giants”, “stories about fairies”. It may have had “A Great Big Book….” or “The Big Book of….” in the title. It was large print with pictures here and there.
