After much searching without finding anything that met my needs or budget, I instead inherited an old Longchamp bag from my sister in law. I LOVE this bag - it's big, but not too big, sturdy, and definitely more work-appropriate than my handmade tote. The only downside is the interior pocket. Or rather, lack thereof. There's a small slip pocket, but it's oddly placed at the very top of the interior right along the zipper. And since it has no closures, everything I put in it winds up at the bottom of the bag by the end of the day. So, I made myself a pouch!
It's perfect for holding on my essentials (pens, post-its, chapstick, hand lotion, mints, a curious kitten's tiny head, etc.) and I can just leave it my work bag so no matter where I'm working that day, I'm sure to have everything I need. (I used Noodlehead's open wide zippered pouch tutorial, size M).
I have to admit, every time I take this pouch out during meetings or trainings, I clandestinely glance around hoping everyone is staring at it. So far none of my coworkers have commented, but I'm sure they're all wishing they had a fancy, unique sushi pouch too!
