One of the things I miss about living in Los Angeles is the downtown fabric district. I spent many days with either my girlfriends, Rick, family, or solo navigating the streets for fabric, baubles, flowers, and design materials. I even found parts of my wedding dress fabric in the garment district (which I will be sharing with you soon).
When I lived in Pasadena I was able to take the metro and not worry about parking. I would pack a large tote with all the necessities water, snack, sanitizer, money, and sunscreen.
Baggu makes functional well designed and durable bags. Perfect for any elements such as dirty bathrooms and what is best you can can wash the bags (except for the leather Baggu).
