I have a near finished quilt top and am getting psyched up in quilt it. I've only quilted one other time and I made diamonds. What would you suggest for this quilt top? I based it off another quilt I found online but it had really cool fluid freemotion shapes which I'm definitely not ready for. Also what color thread would you use? Cream like the materials or Brown like the strips. I could also just do ties, but I'm not sure if that's too "simple" for this quilt.

The quilt will also have a brown border which will bring the finished size to a tiny ~30"x36" - just right for a baby boy.
Thanks for your help!
