I understand what you mean and you might want to take a look at Charismah's QB tutorial on Quick machine binding with flange. It uses 2 strips to add a liitle extra pizzazz to an all machine binding. One strip of binding is cut 1 and 3/8 and the other is cut 1 and 5/8 and you sew them together. You would be doing something similar on your blue with muslin binding.
