I love your bag. I'm not very skilled at knitting, but the times I've had to make one, that material has been much easier for me to work with. In Argentina, we call it totora; I don't know why, but that's what it's known as. It's a great idea to add a lining to that type of knitting because sometimes they end up feeling huge and hollow.
Honestly it’s a great add with the lining, that’s a cute name for it actually it’s plain t shirt yarn here yours has more personality, I think it was hard since it was my first try subsequently it felt easier.
I had never made a chain before when I knitted it, so it was easier to understand with such a large piece of material. I feel like the yarn doesn't slide easily, but it's a good material for upcycling projects. It's on my list of projects; I'm sure with a few pieces you'll be able to master it and make really cute things.
