Textile Designers...I need career advice....?

Thanks for reading this. I have a problem...I just graduated in May 2011 with a degree in Art History. I've always been interested in textiles but I had already chosen my major by the time I even considered it as an option. Now that I've graduated and I'm doing the job search, I realize that, although I love art history, I'd be much more suited in a design career. My question is would it be wise to go back to school for apparel and textile design, or should I consider entering a Master of Science degree since I already have a Bachelor's degree? What would benefit me more? And whatever I decide, do you have any career advice? Thanks in advance.
