Bento Ballet Bag.
I found this tutorial for a little tote bag that I totally loved: the Very Shannon Origami Bento Bag. I've already made three and need to make at least three more. I made two for RG and JE for their dance class bags, and one for a friend as her birthday gift. My other three girls want them too - SM also takes dance but I haven't gotten her bag done yet because I had to do the birthday dresses first.
Anyway, the original tutorial mixes 3 different fabrics and doesn't line it. I used one solid cut of fabric and lined it to give it a little more strength and just for better looks. This is JE's bag. RG's bag has the same plain pink lining, and her's is pink with white Swiss dots on it. The birthday gift bag was a couple of shades of purple. Also, on the gift one, I left off the box corner seams so it can be reversible. The box corners do give the bag better shape, but it's fun to have it reversible.
And here's little Miss JE coming home from her ballet class with her bag carrying her shoes. Hooray for dance class! And she loves the bag.
