I have bought bamboo sheets for years and have always been so very satisfied with the product.  This time two sets of sheets that I ordered came in  and they were too big for queen but too little for a king, just misfits with huge pillowcases.Had to tuck them under the mattress to get them to fit tight.  Never have had this problem before.  Very disappointed as I always get several of my friends to purchase when I see a sale. Now they too are disappointed.
