Sorry to hear you are seeing the pocket. Others can chime in, but I think that’s just part of the aging process and as you use the bag, especially depending on the type of leather.Thank you so much for sharing!! I will do this now! How are the backs of your Bs? I store mine on its back with pillows inside but I’m starting to see some indentation on the back from the pocket and zipper! I will try it with the memory foam and air pillow in between the handles!
There are disadvantages to all types of storage. Laying down can cause more visible pocket. Standing up allows gravity to play on your bags shape and the corners on Bs can sag a bit. If you stuff it too full, that can also contribute to the pocket indent.
Overall, I say just pick the way that feels best to you and most effective for what you want your bag to look like. If a little sag is OK and you don’t want the pocket, stand her up!
