Yes, it’s still July. But your dolls are happy to dress as Harry Potter characters even when it’s not Halloween! So I present to you:
And if your dolls just NEED one too here is the free: Hogwarts robe pattern. Basic sewing knowledge is assumed but it’s a pretty easy pattern. Make one of the main fabric, one of lining (satin in your doll’s house colors would be nice) and sew together. If you have problems, post me a comment and I will try to help. If you have a .pes format embroidery machine, I am also happy to share the embroidered crest I digitized (which for some reason won’t upload here) for personal use only (not to put on things you’re going to sell) .
Enjoy!

The crest truly makes the robe. Nice!!!
I would love the pes file! My machine can read it. justqltin@bellsouth.net and thanks for a super idea and project.
I love the crest also and have an emboidery machine. I can use/convert most formats with my software. Thanks. jmorse22003@yahoo.com
