Well I have a few bags to show you! I made two identical bags like this (see Anna's tutorial for instructions) a while back but kept forgetting to post a picture. I made one for my mom and one for my grandmother.
For my stepdad Mark, I used Anna's tutorial except I didn't gather the background fabric. I used my machine to write a message on the inside of the bag.
I like to keep those tiny plastic bags that extra buttons or thread come in when I buy a new pair of pants and the like. I was keeping them in a sandwich size Ziploc bag and decided to make a small fabric bag with a snap closure for them. Below is what I came up with. I didn't use a pattern - I just improvised!
