I tried a patchwork style. It includes cross-flower stitching, hydrangea, kagome patterns, etc... It can be used as a bag-in-bag or an outing bag. I also added a magnetic snap. A 6cm diameter, 18cm tall water bottle fits inside as shown in the photo. Pens can also be stood up together. The outer pocket has a snap and is divided into two pockets. It's large enough for a cell phone. There are also two inner pockets. D-rings are also attached, so you can attach your own straps or keys. Thick interfacing is used, so it stands on its own. This is handmade by an amateur, so there may be some unevenness or uneven stitching. I would appreciate it if you would consider this before purchasing.
