I've Been Wanting To Get Into Bookbinding But I'd Need To Work On A Setting Up The Printer And Sewing Basics First - Tumblr Posts
Want to fanbind? Need davy boards/book boards and low on funds? I have an excellent hack for you:
Repurpose shitty books
"But!!!" You may say, "no book is shitty! All human experiences are worth putting to paper!"
You're right! But, also, Counterpoint:

I went to my local thrift shop and got these for the low price of $5 for all 10. ("Getting into politics?" The lovely ladies behind the counter asked me. "In a manner of speaking," I replied.)
Once I got home, it was easy to turn them into this, their component parts:

("Please stop saying you're skinning them," my partner begged. Too late!)
[EDIT TO ADD: Here's a guide! Also on my tumblr. Also - when thrifting, bring a piece of paper folded or cut into the minimum size you need for boards: this way you can make sure you're getting big enough material!]
While these are just book boards, diligent deconstruction can even yield headbands, I'm pretty sure - I'll report back on my next trial run. [EDIT TO ADD: yup, you can!]
I cannot overstate the delight I have in giving these covers new life for binding fanfiction, particularly the queer kind.
Happy binding!
