While making these projects, we listened to Traditional Japanese Koto Music. While I would like to say it was enjoyable, I must admit it made me feel stressed, but we finished seven of the tracks.
The first project we made were paper lanterns. I found the directions here. I found the same origami paper at both Michaels and A. C. Moore; it was considerably cheaper at Michaels ($2.49 vs $3.99).
We then made these wooden frames with the same pack of origami paper. Directions can be found here. The boys picked out their stickers at A. C. Moore. The origami elephant you see next to the frame is from this pack which both Michaels and A. C. Moore carry.
Finally, we read the book A Carp for Kimiko and made paper carp kites. The directions can be found here.
