Hi everyone! Fairly new to quilting. I made a small quilt using the 3 dudes quilt block using "Natures Basket." Now my dilemma, I don't know hat thread to use for quilting the top. The backing is a dark navy. The top consist of navy blue, light blue, tan, brown, dark brown. I want to do outline stitches to accent the diamond shapes. Can't post a picture, they are on my ipad, maybe later if necessary. Any help would be appreciated
