I don't wish to be negative about this but wrapping a baby like this in a capsule or car seat is not recommended. We had a case here in Australia where the baby slid out of the seat in an accident and died. Another one because they were using a secondhand capsule. This baby died also and it was only eight weeks old.
The advice given was to strap the baby into the capsule first then cover. With using second hand capsules it was recommended to have them checked by an expert.
The blankie is cute but just wanted to pass on this information as two precious babies never made it.
I do not think you read the tutorial. It shows the baby is strapped in and could not slide out. Maybe they have something different in Austrailia, since i am not familiar with the term capsule used in a baby product. Love this idea.
