I decided to make a short necklace with the first and last braid at 3 inches. The 7 middle braids are each 2 inches. I used silk. I was OK not using 2 alternate colors. It didn’t make a difference when braiding. I didn’t quite match my colors side to side on the necklace to make it even although I tried. I loved doing this class. The directions were very clear. Thanks again Carolyn!
