Go raibh maith agaibh. I don’t really know which would be more appropriate. They’re like miniature blankets, generally kept on the backs of sofas and chairs, to cuddle under when watching tv, etc. I hesitate to use the word blanket, though, because “blanket” brings to mind something much larger. They’re not really clothing (although I’ve been known to walk around wrapped in one when the house is cold). Perhaps furniture throw would be a better term. But does that have the connotation of slip-cover?
