Little giant's shorts are from my all time favourite book, Intemporels pour bebe, Astrid le Provost
Little Giant's hat is the Basic Bucket hat, little Pipa's hat is the Summer Blossom Sunhat, both from this excellent book if you like to sew hats!
And finally my biggest niece hat is the Reversible Hat from Making Children's Clothes, Emma Hardy. (She is so beautiful and the hat is great, the fotos don't make any justice to both. She was with 40 degrees of fever, there are no miracles)
And that's it! You can find all the books in amazon...
