Inktober begins tomorrow and I'm participating this year. I'm terrible at these challenges. I just don't stick to it, but as Yoda would say, Try, I will. Here is the official website.
I used Neenah Solar White 80 lb paper for the guts. It's a very smooth cardstock - nice for pen work. For the cover, an old composition book cover was sacrificed, the black and white is fun. I used black masking tape to hold the covers together, Duct-Tape Book style. This book is simply bound, using the 5-hole pamphlet stitch, here.
Here's the video tutorial. I've linked all supplies below the video, including some of the pens I added to my pencil case video, here. Enjoy!
Here are affiliate supply links. I get a percentage of the sale at no cost to you. Below are JetPens links (no affiliation except free supplies which really helps me out).
