Good question. I have a king bed and most throws are too small. Any ideas?

Pottery Barn offers an oversized throw in 9 or 10 colors. http://www.potterybarn.com/products/monogrammable-acrylic-throw-blanket/?pkey=e%7Cthrows%7C136%7Cbest%7C0%7C1%7C48%7C%7C1&cm_src=PRODUCTSEARCH

If you don't use a throw, then you can use a quilt, blanket, coverlet, or duvet, folded across the foot of the bed.

I like a comforter, duvet or throw that at least reaches the ends of the top mattress, if not actually tuck-able. I do know that if you want to achieve that for a Queen size you need to order a King size cover. No idea what people with King sizes do.

Thank you Carolyn!

Thank you for your help. My question has been answered.
