Having a smaller group does influence the pages done per person, or left blank to fill in yourself or through 1:1 trades. If the group wanted to divide the pages equally, 30 divided by 8 players is 3.75 pages. Everyone could do a 4 page spread, or a couple could opt for just 3 since there's not quite enough pages for everyone to do 4. Or everyone could still do 3, but the book owner would have more freedom to decorate and establish the theme at the beginning of the book, and then a couple pages to wrap it up at the end.
I do have some sad news, theweavershand will not be joining us for this round. There is one person who pm'd me saying she was interested in joining, though I wasn't sure if you all wanted to keep the group small or what. It sounds like finding a replacement is preferable?
