I cut out a template, sort of bowl shaped, but not for any reason, I just wanted something big and not square. Then I started adding strips of white fabrics to it: synthetic chiffon, muslin, scrim and cotton gauze. I then added fine layers of Rambouillet. This photo shows it wet down and it's just started to felt:
Once the resist started to curl and I knew it was properly felted, I started to full it on bubble-wrap. It really puffed up!
I removed the resist and carried on fulling, I turned it the right side out, and realised I’d accidentally made a felted cow stomach!
I tested to see if it was fulled enough by inflating a balloon inside, then carried on fulling until I was happy with it. This isn’t the best photo, but you can see the shrinkage, compare it to the first photo - it started out the full height of the netting:
