I finally came up with a solution ... stuff it with towels ...
Voici, the top of the hat
I first placed an open small towel and stuffed the other towels inside the cavity. The key is to get it nice and smooth.
The trick worked perfectly. It has now been delivered to the recipient ... just in time for his birthday.
Here is the handsome, goofball modeling his birthday present LOL ....
I do hope you find the hat blocking trick useful. I would certainly enjoy hearing how you go about blocking a hat.
Thank you for stopping by my little corner in cyberspace! Cheers!
