You can do a search for Christmas In July (or CIJ or ChristmasInJuly) on Etsy to find the participating shops.
Please come and take a look...it'll be fun singing Christmas Carols in July. You might get some early Christmas shopping done and there'll be no bad weather to fight through to get to the mall. (Snowman up above is just a picture...:) )
