I have finished one book with a silk cover. It is a very fine fabric (60 epi) and liable to fray, even though I ironed fusible lining to it. So the corners of the corner had a smidgin of PVA applied which makes the book look tidy and should hold the silk in place. The paper is watercolour paper. You can just see the blue marbled end-papers that Michael made.
I have another identical book which is half finished but will not be able to do much more until the next book-binding class. It was half-term this week.
What I must concentrate on is the endpapers for the Omar Khayyam book. The problem is gluing the endpapers on to a backing sheet. They get all wrinkled. I have been reading Ikegami's 'Japanese Bookbinding' and came across a different technique for glueing two sheets of paper together for end-papers. I will try that at the weekend. It needs a visit to the cellar which means going out into the snow!
