How about a log cabin in assorted greens from light celery to dark green in combination with different color ecru, light tans, etc. You can arrange the blocks in different ways to suit you.

All greens go together. Sounds a bit odd doesn't it? But think about it, we look outside and see grass, and different shrubs, flowers etc. and they are all different greens. Our eyes like the contrast, and we don't see anything clashing! Now, other colors, are different. Hoffman has some free patterns https://hoffmanfabrics.com/content/c...asp?FolderID=7 Look at the Florence or the Canterbury quilts, both would be beautiful in that room. You can't go wrong with Batiks.

good idea.

Maybe a hunter's star in cream and a suitable green (probably a bit darker than the walls, for contrast).

I think you need to get away from all that green you are not trying to make your room into a cave right? you have bright white trim, something half white blender/tone on tone and the other a lighter pattern that has a hint of a coordinating green not a ton of it overkill is not so good. I think your asking for fabric lines also is that correct? like who makes what layer cake etc that would go with your room?

I'm late but there's a new Stonehenge line out by northcott in greens. One is shamrocks which I bought from fatquartershop.com and they have the sets with just the greens.

I would use McKenna Ryan's Natural Instincts fabric by Hoffman.

What about using colors from his hobbies or job.
