[Source] Hat band findings

Hi, Can anyone give me good U.S. sources for tiny sterling or gold
belt buckles that are used on hat bands and bracelets? Also, I am
looking for a source for alligator, crocodile and other leather type
hat/watch etc bands about 1/4" wide. Or I will cut down scrap lengths
if I have to. Thanks for any input, Sally in unbearably hot Houston.
