Hi all, I am new here. I started a temperature afghan this year. Since the temp obviously changes every day, there was no way to know what I would need, so I could buy all the yarn ahead of time. I chose to use Vanna's Choice, figuring it would be reliable and available. I was wrong!! I can't find what I need anywhere. All onliine sources have very limited colors. I am barely past half the year. Is there some chart somewhere that compares colors so I could choose substitutes that at least come close? Thanks so much for any help you can give me, I am at a standstill.
