Pink always goes nicely with browns. Maybe 2 or 3 shades of pink, plus an ecru.

There is a pattern called "Wickedly Easy Quilt" on the ByAnnie website which is a free pattern. It is an FQ pattern with no matching seams.

There are some sunflower, and brown eyed Susan blocks I've seen done in browns with a little yellow.Just google either word and you'll see what I mean. Hope that helps.

I love working with browns. I don't know about the pattern, but would suggest you add an accent of yellow or orange since those are two of the base colors of brown, which is shaded.

Try the pattern "card tricks."

I am currently making a bow tie quilt using the "10 Minute Block". It is made from brown scraps - 6" squares with a dark brown center, 2 medium browns, and 2 tan or tone on tone ecru. It is looking good so far.
