Snack is a lovely pattern and Tomàs Padrós CZT has created a great step out for it, which includes lots of suggestions and variations.
I have to say, it is a motif I’m familiar with, probably early Celtic art or architecture. It was great fun for me to draw, and in keeping with my rather higgldy-piggldy arrangement I chose to use it in that way. As a nod to the architectural origins of this pattern, to me anyway, I’ve worked with shadow and highlight to practically ‘scuplt each ‘snack’ element. I particularly like the ‘half snack’ versions; again, they are familiar to me but not connected to Zentangle, and there’s nowt wrong with that at all!
