Check out my newest creation. It's a card holder for dnd spells that fits perfectly in Ikea kallax drawer. If you need a different size don't worry! You can customise it to your needs.

My kid loves food pouches but he started squeezing them and food got everywhere, so I decided to take things in my hands and design this holder. This is made so it works with Simple Modern Reusable Baby Food Pouches but it might work with others too.
