Are chunky knit blankets practical or just for decor?

Specialist subreddit threads on interior decorating are split. Owners say the look is great draped over a chair or sofa, but the loose weave snags easily, sheds, and is hard to clean. If you want a blanket you'll actually use nightly, a sherpa fleece or wool throw is a better functional buy and a chunky knit is better as an accent.
