Bats flying against a blue background with barely legible handwritten script. Could it be a diary entry? Lined in gray/black polka dot fabric. Lightly padded, D-ring on the side for a carrying strap, or you can remove it and slide this pouch into your larger bag.
 
Big enough to hold an iPhone Plus sized phone with a bit more room to spare. Recessed zipper closure. Approximate size is 9" across at top widening to 10" at the bottom; 5" tall' 2" deep. Sewn by me using the Swoon Coraline pattern.
