I LOVE itabags! I have three although only one is in use right now. Two crossbody bags and one is black and for Final Fantasy XIV, specifically Red Mage stuff and G'raha Tia. The other one is pink and I use that for magical girl stuff. My third one is a Pokemon backpack that I used to have stuff with Piers from Sword/Shield at the lower half and my favorite team on the upper. I want to make more ita bags but the problem is that I don't have time to go out and about much so instead I just have cork boards set up in my work/doll room and do what I'd do with an itabag on there. Plus, the cork boards tend to have more space and I collect a lot of pins.
I have two that I've bought and one that i need to finish sewing. One of the ones I bought is my everyday purse, and the display window is shaped like a cat head. It's got a few pins, mostly fic tropes and cats. Another one is shaped like a story book, so i put some more fairytale esque pins i have in it (though i could probably add a lot more, it's big enough). And the one I'm sewing is a backpack with a star shaped window that i have no idea what i'll display in it xD The fabric is Disney princess themed though. I have way more pins than i could fit in bags and see often, so I made displays using some white board or sheet metal, magnets, and scrap book paper, and i have a few of those for different themes.
I use a die cut machine carrying case for most of my dolls, but for my tinies, that's not a bad idea!
Oooh that's a good idea!! It's a little small for most of my dolls but they could fit if i tuck their knees up. I hadn't thought of something like that, thanks for sharing!
