I saw Suse RevoluzZza's monsters last night and couldn't wait to get started on them today.
I've made mine out of a remnant of rainbow fleece I found at the market (lucky find at 1.75 for enough fabric to make four!)and felt from a scraps bag.
I've filled them both with buck wheat and lavender so they can be popped in the microwave for a short while before bed to keep the kids cosy. The buckwheat cost 1.50 (suma) from my local health food shop which was enough for 2 monsters if you don't resize the downloaded pattern.
The lavender/buckwheat mix was about 2/3 wheat 1/3 lavender - I have some buckwheat left but I wish I'd stuffed the vertically striped one more as he's a bit saggy.
I'm looking forward to making more, next time I'll have had a little more practise machining the eyes and hearts on, they were a bit sketchy on these two.
