Steeler blanket for my dad

Please help I’m looking for a good crochet pattern for a steeler blanket for my dad he’s in the hospital due to a stroke they found bleeding and swelling of the brain and just a few days ago they started treating him for pneumonia and they sedated him so they could give him his antibiotics and help him stay comfortable till he got better and now every time they try to wean him off the sedative his blood pressure sky rockets and has a hard time breathing so he is doing ok but not where he was at before his stroke Saturday night so I want to make him a steeler blanket to help make him feel more comfortable
