I recently posted a few test folds of pleated tubes. In this model, I’ve used those pleats in a more finished vase-like form. The curve here reminds me of a question mark, or of a swan’s neck.
The triangular shape means that each pleat requires a lot fewer folds and reference points than my previous curved-neck vases with 10 sides. I’m still exploring whether this is a direction I’m interested in turning into a series.
