We will be soon starting this CAL.
This link has the pattern and instructions: http://attic24.typepad.com/weblog/2008/11/hexagon-crochet.html
You can use any colors and any worsted weight yarn you want, but I would not recommend mixing weights of yarns.
I will most likely be using Vanna's Choice (only because I have so much of it).
I need feedback, one hexagon each week, or one step each week??? What would you prefer? Or should I offer both as options?
This will be postponed, but not for long. February 15th we will start this CAL. So mark your calendars and budget your yarn!
