1. The four colors I used in our demo bracelet for this class are orange, green, pink, and white.
2. The pattern I used for our demo bracelet is Pattern #10, a regular chevron pattern with four colors. I used the maximum number of colors allowed under our creative constraint of folding four strings in half to make eight strings, because, with more different colors, you can more clearly see the movement of the strings during the knotting animations and demo.
Here's my finished demo bracelet:
In my case, I also made several other different chevron bracelets in lots of different colors, in both regular and alternating patterns, and one in a mixed pattern, to be able to use the images in my class lessons. Here's one of the graphics from my class that features a bunch of these bracelets:
I'll be excited to see what colors and patterns you choose for your bracelet, as well as your finished bracelet!
