These are great. I love seeing manga and comics in the making process.
Going back a year into his twitter and I see nothing. Where did you find these? Was this for an interview?
That image is what got me into Yotsuba, I had no idea what I was getting into and I'm glad.
I've bought all twelve volumes, its the only manga I've ever bought.
New chapter? How many are we up to? ~150?
I found this. Jpg while looking up Yotsuba on KnowYourMeme
When will we meet grandma?
When it is time for Yotsuba to learn about death.
