Like very brown.
I only bring it up because so many quilters seem to have an aversion to brown.
I've said it before and I'll say it again: brown is good. Brown is your passport to gently changing from one colour group to another, all the while retaining warmth and flow.
Black and white will stop your colour flow. It will make (imo) the quilt less warm.
That said, every colour has its place in a quilt.
|Rather like the quilting going on in that animal print block|
And that includes brown.
