I want to know if this will work for a bargello quilt? What should I change?

I don't see why not. I think the green and blue will add a little pop to it.

do you think i should use 1 more color?

I might throw in a red or hot pink or maybe a purple.

because the third fabric from the right has a larger print than the others, small squares of the fabric will have different looks...if the square hits the white, it will show up as all white while if it hits the darker part of the pattern, it will come across as darker. This will add some variation in the quilt overall - not necessarily a bad thing, but something to think about. All the other black/white fabrics have a smaller overall print so won't produce the same variation.

ok I changed it some how is this?

I'm looking forward to seeing the finished quilt, I think inserting the contrasting bright colors will give the quilt a unique look. Agree maybe one more bright color.

Just saw you added another color. Looks good.

looks nice together - the colors add a lot of pizazz.

I like that! It will be pretty when it's finished.

I can't wait to see pics of your quilt when it's done!!!
