You can find the diagram to this cute model from Keiji Kitamura in the book “Origami Treasure Chest“, page 60 – 61.
To make those cute Origami Bunny Envelopes, you just need 1 square paper and a scissor. The whole Origami envelope is made from only that one sheet, including the bunny. You can use duo colored Origami paper, then your envelope has one color and the bunny is colored in another color. You can also use mono colored paper like copy paper or card stock. Then the bunny and the Origami envelope have the same color. You could draw a funny bunny face on it – if you like. Be advised though, the thicker the paper (like card stock), the more bulky your envelope will be. You probably will need a ribbon to hold your Origami envelope tight together – without opening up from alone.
The Origami Bunny Envelope is an easy Origami project – which makes it suitable for the complete novice. It is also a relative quick Origami project – which can be completed in less than 5 minutes. The folds are also easy to remember, so your second and third try will even be quicker. Be advised though – Folding Origami Bunny Envelopes is addictive!
I made several Origami Bunny Envelopes – just for the fun of it. The smallest one I made was from 8.5 cm x 8.5 cm / 3.3 in x 3.3 in paper – finished envelope was 4.5 cm x 3 cm / 1.8 in x 1.2 in. Medium size Origami paper 15 cm x 15 cm / 6 in x 6 in – finished was 8 cm x 5.3 cm / 3.1 in x 2.1 in. Large Origami paper (20 cm x 20 cm / 7.9 in x 7.9 in) resulted in 10.5 cm x 7 cm / 4.1 in x 2.8 in. And the largest Bunny Origami Envelope I made was from 30.5 cm x 30.5 cm / 12 in x 12 in card stock. The finished envelope measured slightly more than 16 cm x 10.5 cm / 6.3 in x 4.1 in.
