Extension posts... To use or not to use? I have two 12x12 postbound scrapbooks that I'd like to combine into one, if possible. It really is one book that I split into two because it got too thick. All of the pages have foam adhesive squares or foam embellishments, which have added to the thickness overall. The covers are popping up! Book 1 has 8 protectors/16 pages, and Book 2 has 7 protectors/14 pages (a total of 30 pages for one book). Yikes! I've tried no extension posts, 1/2" posts, and 1" posts -- nothing seems to solve the problem. I've expanded the spine -- no luck there. I've taken off the clear album protector (which really needs to stay on, if possible, to protect felt alpha stickers on the front cover) -- also no luck. The covers keep popping up on the two books -- I'd hate to see what would happen if I combined all contents into one book! What am I doing wrong, besides using foam on every page? Too late to fix that. Help, please? One book, two books? Which posts, no posts? My goal would be to get the spine end to lay as thick as the open end and, hopefully, do it in one book! Thanks for any suggestions!
