there is no difference between lavender and self blue.Thank you for posting the photos...I've been wondering how Lavender really differed from Self-Blue and Porcelain (ugh, I can't spell it without spell check). They kind of look Porcelain but with some tan/brown at the shoulders (that part might be the Milli coming thru however).

porcelain is the millie fluer pattern diluted by the self blue gene
