Spekled: I would probably go with all the same type of yarn. If it is anything like thread it will give you problems with mixing and matching. Either way it will be beautiful. I love sampler afghans.
I think I rather agree on the type yarn. I'll have to get more of that when we go shopping this week. Need more of the teals, sage greens, etc anyway. I have some but the wrong shades of green and blue and what I do have is a dull finish. Still thinking on this one. Thanks for all the input, ladies!
