I have a 4yo and a 1yo, both who require 'stuff' when we go out. Not as much stuff as when my youngest was a newborn, so I don't need a big diaper bag anymore. But more stuff then will fit in my little day to day purse. So what's a mom to do?
Make an inbetween bag! I used this awesome tutorial, and I love love love my new bag. It fits all the things I need to carry (diaper change kit, drinks, snacks, my stuff, some toys, plus the little bit of stuff I carry. I added four inner pockets (one is for my cell phone) and a key ring so my key's don't just fall to the bottom. It's a magnetic snap so it's easy for me to just reach in and grab something. The strap fits comfortably over my shoulder so that I can have my hands free.
I used some lightweight fusible interfacing to give it a little structure/body without making it stiff. The strap I basically just made a wide binding strip instead of turning a tube (so much easier). I used about 3/4m for the outer, so with the leftovers I'm thinking of making a matching zipper pouch and tissue holder, etc.
Love my new bag!
