The higher the contrast...the more the bobbles will show. Ask me how I know! I like the 1/4 on the top picture. I would pick either a slightly darker neutral or a lighter pink on the 2nd. (the white is too light...and the pink too dark) Not sure about the dark border..maybe even one of the greens..and the lighter green in the last. Your colors and piecing are very nice...if it was me, I would want my piecing to stand out and the quilting to be a supporting character. That being said..its YOUR quilt, so YOU need to be happy with it! ..I think I have that panel of sayings!
