It's been a while I did any mayor cross stitching. But currently I'm listening the the two first books in the Stormlight Archive Sage by Brandon Sanderson, and they both are very good, and very long, and excellent to do cross stitching to.
The pattern I'm doing is called 'Honour Diversity' (the link I have in the side bar is not working any longer - sorry about this, but I can't find any place right now that carries the pattern). I've got one of the dolphins done and the two sea turtles and now I am working on the big fish. No back stitching done yet, and there are also a ton of french knots, which will have to wait until the end.
