Thank you Mimmy! I'm not really bothered by the unstructured nature or the waviness but based on the photos and videos I've seen online I haven't seen anyone's pico are folded in so much so just wanted to get some comfort that it is normal and it sounds like it is. I'm definitely going to use an insert to retain its shape.
btw, your pico looks lovely too!
