Instructions for the model were published in Tagungsband Origami Deutschland 2025 (German convention book), on pages 34-37.

No instructions for this model were published, but it is mentioned in Shuzo Fujimoto’s Twist Origami I on page 10 as model “No 28”. It appears as a textual comment near the instructions for CFW 110 (marked “No 27”) saying that the center is to be changed from “No 1” (Windmill (CFW 84)) to “No 2” (Petals (CFW 85)).

This model is almost identical to Hiroshi Kumasaka’s Heart Card aka Heart 2. The only difference is the layer ordering of the paper behind the heart proper. You can find instructions for Kumasaka’s model in:

• NOA Magazine 66 (02-1981)
• Le Pli 62-63
• This video tutorial

A video is available from OrigamiUSA (for members only).

Also, check out the instructions for variant B, which is very similar.

This model does even have a picture in Fujimoto’s books: it is only mentioned in one sentence as the possibility of combining CFW 133 and CFW 85. It is listed as “No 51” on page 13 of Twist Origami I.

A picture of this model and the starting twist were published in Shuzo Fujimoto’s book, Twist Origami I, on page 10 (labeled “No 26”).

A CP along with some notes for this model were published in Shuzo Fujimoto’s book, Twist Origami I, on page 24.

See the instructions for Well I.

Instructions for this model were published in Shuzo Fujimoto’s Twist Origami I, on page 23.

Basically, you start with an equilateral triangle of duo paper, fold the three corners to the center, and then proceed with folding CFW 120 from the resultant hexagon with color change. Due to the extra layers, you need a rather large sheet to fold the model conveniently (the triangle’s height is 1.5 times the height of the hexagon).

Instructions for this model can be found in Shuzo Fujimoto’s book, Twist Folds, ISBN 9784416312001, on page 39.

You can also check out instructions for variant A since the difference is small and easy to find out on your own.
