This is amazing.
Those are super cool, and I've actually been thinking about printing out stuff like flags and propganda posters lately, so it's perfect timing for me. I think I have some dowel laying around somewhere from another woodworking project too.
Off-topic: This is also the best example of what I consider the "right way" to do a blog post here I've seen yet. You give an introduction, the link to the tutorial, and a picture that makes me want to have a look.
Sincerely, thank you for sharing this.
