My parents and I have a running joke about different shades of thread. This stems off a needlepoint project Mom did years ago of a Siamese cat on a pink pillow. There were quite a few different shades of pink, and she got frustrated more than once.
This project has three shades of blue, one of which they tried to disguise by calling it "blue gray", and two shades of pink. I had fun separating the pinks and two darker blues.
Anyway, I will be continuing the wolf project shortly. It is slowly coming along. I cannot give a decent estimate on when I will be finished with that one.
