Those hats are adorable. One suggestion, someone asked for a larger photo - I'm sure it's not in this case, but often people figure out the pattern from a large detailed photo.
My only other suggestion, the larger size could be a bit deeper and come down a bit on the forehead to protect the eyes a bit.
I'd ditto the suggestion of pricing the patterns, and being able to buy them direct and downloading them.
Keep up the good work,
