Donzi Patches for Mooring Cover

[Northern Sweet]

I am getting a new mooring/trailer cover made for my 16' Donzi. I am getting it custom made with top quality material. But, from a distance it just looks like a blue cover. I would like to personalize it and get some Donzi lettering or logos that I can get sewn on. Anybody have any ideas where I can go to get such things??? The cover is navy blue, so white patches would be ideal.

Thanks
