Questions
Does a higher thread count mean better quality?
Not past a moderate range. Single-ply long-staple cotton at a modest count beats a multi-ply cover with a high count.
Should the duvet cover be the same size as my comforter insert?
Yes, the same size or slightly smaller, so the insert fills the corners.
Bedding Duvet Cover Sets
A duvet cover set is the same cover bundled with matching shams, so choose by the same weave, fiber, ties and closure criteria. Check the sham count: twin sets usually include one, larger sizes two.
