Wanted something to have my money stored in when using the market bag and did not want to dive looooow in the bag to find it. Inspired by this project of paperdag, I just single crocheted two grannies together (sunburst front and back is simple target square, as used in Ingas Häkelbeutel, but with hdcs). Used the hook from one of those badge holders you get at trade shows and congresses to get it attached to the bag. quite useful! Did not add a closure on purpose, as I wanted to be able to just slip the money in.
