Flower Box ("B" version) is a clever one-sheet container! The box appears to have three layers but is actually folded from 1 square sheet of paper with no cuts and no glue. You should be comfortable folding a blintzed waterbomb, open squash and petal folds. The depth of the box can be adjusted to a deep box or a shallow box. The Flower Box can be gently flattened for transport.
In class, I will provide 1 sheet of 24 cm (~9.5 inch) plain kami for folding.
All dimensions are approximate: folded from 24 cm square sheet creates a box 17 cm (6.75 in) length x 17 cm (6.75 in) width x 5 cm (2 in) tall.
Folded from 15 cm (~6 in) = 11 cm (4.5 in) length x 11 cm (4.5 in) width x 3 cm (1.25 in) tall.
Folded from 10 cm (~4 in) = 5cm (2.25 in) length x 5cm (2.25 in) width x 1.5cm tall.
