http://karenlynnebeads.blogspot.com/2013/07/mom-daughter-challenge-1.html did the first challenge to use a color and stitch we normally don't use.
I was trying some Tunsian Crochet and a new stitch called a puff stitch and decided to use pink-a color I don't care for. It really was a challenge. First I tried to do the second row in the wrong place but didn't realize it until the scarf was 8 inches long and very biased. Then I kept repeating the rows in the wrong order. Finally, it clicked and the scarf is done. Repetition does help in learning. Now I need to find someone to give it too. I don't wear pink.
