It is difficult to make a recommendation without seeing some of your blocks and the colors that are in them. But, I would suggest that you lay your blocks on a small piece of what you are considering for sashing. Step back and snap a photo. Often seeing through the eye of the camera will help you make a choice. Pick up one of the colors from the blocks and replicate it in your sashing. In the end, choose a color to please you. A color that will make you go "Ahhh, perfect."
