I learned in a college art class a long time ago to arrange your colors in an "earth to sky" setting, for example your darkest colors, like blacks and browns at the bottom, work your way up to yellows, light blue, white at the top. Greens, reds, orange, pink, purples in the middle. Makes your eye gently flow up without a harsh demarcation. Ever notice how a vase is usually shaped narrow at the bottom, wider at the top--kinda like vapor dissipates as it rises. This is how I try to set my colors when I'm overwhelmed, and it's always worked for me. Maybe this will help you.

What ckcowl is saying - -

When I do the 'blurred vision' thing - the greens 'merge' into one color - the same thing happens with some of the other colors -

I'm not sure if I can post this link, but this is the quilt I was trying to replicate

Your fabric arrangement is much better this time, but the pale green and mustard yellow right after the dark brown still seem out of place.

I think you could probably use your first three in the top row in the sequence after the dark gold or between the orange and the dark brown. It seems like there needs to be more browns in the sequence if you are trying for the Amish one you linked to.

Getting everything in its proper place can be both fun and frustrating. Lol! But well worth it.

This is going to be very pretty!

I agree with dunster. But your values look a lot alike. You need to have lights, medium and darks. I don't necessarily agree that you only have to use two colors in Song Surf. But you do need variation in values. Sometimes it takes me months before I am pleased with the results of the fabrics I picked. I would also suggest you lay out the width of your fabric and see if that is pleasing to your eye. GOOD LUCK!!!
