I have a large tote that is serving as a workbag. It's a nice Liz Claiborne with good storage in the pockets. However, lately I am finding I cannot keep it on my shoulders for very long, even when it isn't really full (wallet, daytimer, cosmetic case and phone). Do I really need a big bag for everything? I have my client files that I carry back and forth from home to studio and plus what I mentioned above. Even though I don't work from an office, I entertained the thought of a briefcase. At the same time, I don't want to carry too many things. Any suggestions? Thank you so much.
