YouTuber nekomewleta has a great little video tutorial for making an insert for your ita bag that will let you easily add and remove pins and other merch. You can make multiples to switch out as your mood strikes!
This method works perfectly with any of my ita bag patterns!
Instead of using a towel for the padding, I recommend gluing a layer or two of cotton quilt batting to the cardboard instead. Batting is easily cut to the shape you want, and if you glue it down, you won’t have to worry about it shifting or bunching up underneath the fabric.
Thanks for the great tutorial, nekomewleta! Subscribe to her channel here!
