Thanks for the responses. It sounds like either the dream green or the Hobbs 80/20 would work well. Now for another question:
Should I plan on quilting it fairly densely since I'm assuming it will be washed a lot? Or is it okay to do less quilting (say 3 to 4 inches apart)?
Also, I usually use either Isacord (good strong polyester thread) or Aurifil (cotton, not quite as strong) for quilting quilts that are to be used. My question is whether the Aurifil will be strong enough to handle lots of washing.
And also, someone mentioned in a post recently about not using a certain kind of thread because of some danger to babies getting their fingers wrapped in it????
