Wow, these are amazing. I really want to learn bookmaking. You say you're from Aus, as am I, where did you buy your supplies?
Sorry -- work has eaten my life the past couple of weeks, and I haven't checked in here until now.
Where in Australia do you live? I'm from Melbourne. I buy all my supplies from specialty art shops. Some came from Melbourne Etching Supplies
on St David Street in Fitzroy, just off Brunswick St. A lot of the papers (the black paper, the red tissue paper and the paper used in the pages) came from Neil Wallace Printmaking Supplies
on Greeves St in Fitzroy. Most things came from Melbourne Artist's Supplies on Little Latrobe St in the CBD, right near RMIT -- they have the largest range of bookmaking supplies I've come across in any of the stores so far -- bone folders, awls, archival glue, thread, Chicago screws, board, etc.. I also bought the Japanese chiyogami papers from there -- they sell them in A4 size for about $3, or a very large sheet for just under
