Step 1: Materials
- origami paper (one square per koi you're making)
- wire (not too thin; I used 20 gauge)
- hot glue gun
- (optional): string
Step 2: Folding the koi
For making the koi, designed by Sipho Mabona, I used an online diagram (whose link doesn't work anymore for some reason) and a stop-motion video of the folding process so have fun! It's pretty tricky, especially the swivel folds, but feel free to comment below if you have difficulties and I'll try to help. Fold as many as you want, but I folded 39 of them: 1 white, 2 bright yellow, 3 yellow-orange, 2 dark orange, 2 light orange, 7 red, 2 pink, 5 purple, 2 dark blue, 5 medium blue, 4 sky blue, 1 dark green, and 3 leaf green.
By the way, this link might help.
UPDATE: This is a link to a video tutorial for folding the koi; it'll make life a lot easier than following the stop-motion video. Thank you to DrGaf for bringing the video to my attention. ^^
