A blanket designed for temps below 30 degrees (F) would be ideal. PREFER a blanket with front straps, not a pullover BUT will consider all offers, depending on price. She didn't have a problem putting the "test" blanket on her but it had the front buckles. Not sure how she'd do with a pullover.
I can get a new one online for about $40-$60 so I'm trying to find a used one that's cheaper or a better blanket for the same price. $20-$30 would be ideal ! Yeah, I know, I didn't think ahead apparently!
