I have 3 boxes of Butterick patterns that I am getting rid of. I make little girls clothes so I am sure there are at least 1 or 2 that are the size you need. All patterns are new and uncut. If you would like to email me your address I would be more than happy to mail you a few. My email is sleepysbabydoll@gmail.com

Hi Mary,You should Google your requirements, you would find more free patterns than you would ever need.
But the link below is the first place I look, it is free to sign up and they never bother you with emails.
Enjoy!
Anna Bove Embroidery has a cute dress made from linen handtowels. Maybe you can make a small one? It is so cute!
