I happened upon this site, it is a treasure trove of patterns and they are all free! The illustrations and the pattern are usually included on all items.
"Godey's Lady's Book" is filled with wonderful items to create, this link is to a full page of free patterns for children, men and mostly ladies.
As a side note, this boy's pattern is large enough for a female adult. I would wear this, it is a wonderful design.
And I would love to wear this! Talk about haute couture, for little boys?!
Here is another link to more of Godey's thanks to Hope Greenberg for all her hard work providing this material!!
