Except in the case of Blunt's Love Lyrics, The Nature of Gothic, Biblia Innocentium, The Golden Legend, and The Book of Wisdom and Lies, a few copies of all the books were printed on vellum. The six copies of The Glittering Plain were printed on very fine vellum obtained from Rome, of which it was impossible to get a second supply as it was all required by the Vatican. The vellum for the other books, except for two or three copies of Poems by the Way, which were on the Roman vellum, was supplied by H. Band of Brentford, and by W. J. Turney Co. Of Stourbridge. There are three complete vellum sets in existence, and the extreme difficulty of completing a set after the copies are scattered, makes it unlikely that there will ever be a fourth. The black ink which proved most satisfactory, after that of more than one English firm had been tried, was obtained from Hanover. William Morris often spoke of making his own ink, in order to be certain of the ingredients, but his intention was never carried out.
