Step 1: find and hold a blanket or something of the sort. You’ll need to hold it like a vampire holds their cape
Step 2: wrap it around yourself like a towel, but over your entire body. Make sure it goes over your shoulders if you want to get up and walk somewhere, or tuck the top part under your arms if you want to drink tea or something. If you’re sitting down, kinda unfold and push the top flaps out of the way if you’re working on a desk. This is probably getting confusing, so just do whatever until you’re comfortable and you can do what you want to do.
Step 3: stay like that, sit down, or lay down. Very comfortable, right?
And presto! You’re a blanket burrito.
