Thank you so much for liking my large brimmed hat.  This was the first hat I made when learning millinery.  I thought it was quite a challenge, but got there in the end.  I am sure you can make one for your granddaughter's wedding.  I just made one similar for a lady who was mother of the bride.  Slightly different  decoration.  Absolutely terrified when approached, but I did it, and it was delightful and she loved it.
