Coptic Stitch Bookbinding!
The top two photos are ones of my own, displaying my watercolour sketch book I made several months ago using the tutorial I’m linking to you guys, with a few modifications. I made my holes a little more spaced out, but if you were to do the same, I’d make sure the side ones were close enough to the edge. My corners sometimes bow out because there’s not enough support on them. Also, I added a latch thing to keep it together, similar to the type you’d see on some envelopes.
I used SeaLemonDIY’s, “Bookbinding Tutorial: How to Coptic Stitch”.
While you’re watching the video, go check out her other tutorials. They give you insight to other methods of bookbinding, creative things you can add and change to your technique, alternate tools, and other really cool how-tos. Not to mention, the videos are very easy to follow and well edited.
Good luck with your bookmaking! Thank you!
