Thought I’d share my tools of zentangle, of course art sketch books and the above. I’d say its cost about $50 to get what I have including folders, shoes, etc.
I’d have to say though out of the whole lot the my top 5 items would be
1. 6h pencil
2. Fine tip black pen 0.4
3. 6b pencil for shading
5. Pencil sharpener
So I reckon for about $10 you could start zentangle art
