This is how to make a bag insert! 👜 The pattern pieces for this project are super simple. And if you want to go the extra mile, you could add additional pockets & maybe finish the edges with binding tape (although you really won't see the raw edges once it's inside your bag). This is a great solution to add structure to flimsy tote bags as well!, and the felt is super light, so it doesn't really add any additional weight you have to carry either.
