I bound my first ever book! It's a little 5 hole pamphlet bind with some old printer paper that got bent when we moved. The cover is 100lb/270gsm acid-free cardstock. I used unwaxed linen thread to sew it. There's 10 sheets/40 pages in total. I wanted to make something simple that I wouldn't be afraid to mess up before trying any real fanbinding.
Definitely the messiest part was trimming the pages. Sanding it down afterward helped a lot, but I think I need a better/sturdier knife than my little craft blade.
For a first attempt, I'm really pleased with how it turned out! Not a huge disaster at all. Also, I discovered that the long thin trimmed bits of paper are irresistible to my cat, especially if I trail the tip through her whiskers.
