When i have done a quilt with lots of color I use verigated thread with colors of fabric as close as possible.Or I will use verigated thread that will stand out.Dependinding on design in quilt I will go around charectors and pieces to accent them then finish with the s squiggle pattern that most people have on their machine stitches.Please excause spelling.Have fun with your quilts and dont worry about what others think.These are your creations for you to enjoy doing and giving.
