## Questions & Answers

**Q: Which cover do you recommend for a 108x94in duvet insert?  It seems right between your king and oversized king sizes.**
A: Oversized king!

**Q: Is the pure white duvet cover see through or is it thick? My comforter has a yellow tint and I do not want the yellow to show through the duvet cover**
A: This will cover it well - fabric is not see through. Thanks!

**Q: Will this keep feathers from leaking out?**
A: Really like this duvet cover.  The fabric is fairly thick so I would think feathers couldn’t leak out of it.  I’ve never seen a feather escape this cover.
Durable and machine washable also.

**Q: Does the king duvet cover fit a California king bed/duvet?**
A: Hi - Our King Duvet Cover Set measures 112" x 90"  - so please review the measurement of your duvet ( on its wash label) to see if this will be sufficient. Thanks !
