Leather in Florence

I like the leather school in Florence: https://scuoladelcuoio.it/en/
It's right behind Basilica di Santa Croce.

I second the recommendation for the Leather School.

For jewelry:

For jewelry (not precious) I'd recommend Angela Caputi:

She might be the most well-known name in the city for costume jewelry, and her works have appeared in in fashion magazines in many countries for decades. She has two shops in Florence.

I recommend Papini for leather. Good quality and very nice staff. When I wanted to buy jewelry, Cecilia at Papini recommended Vaggi, which is located on the Ponte Vecchio. Vaggi is a family-owned business as is Papini.
