Finding my “value”

I have been listening to the “money” series and feel really happy with the principles that Brooke is teaching. However, I am struggling to apply the “value” element. I understand that most people use time and effort to dictate how much money they could potentially make and this limits them, but this is my situation….. I design and make childrens clothing and there is only so much i physically produce and charge per item, therefore I am racking my brains to how I can add more value to my business that would generate more income? I understand the thinking of adding value with a business like Life coaching as there are so many different arms to the business model and so much value through podcasts etc.. but I’m trying to figure out what my equivocal value would be. Am I totally misunderstanding the “adding value” section of what Brooke teaches?
