I recently made Samantha's Pinafore as a gift for a blogging friend. I used the Samantha patterns from Pleasant Company/American Girl, which were given to me by this same sweet friend. ;-)
It is modeled by my Samantha doll, but I haven't made the birthday dress it is meant to be worn with, so the dress pictured is the Pink Edwardian Party Dress, for sale in another post, and in my Etsy shop.
If you would like to special order Samantha's Pinafore, please email me at thewelldresseddoll@hotmail.com.
I can also make Samantha's Birthday Dress and the Lacy Pinafore as a set. :-)
