A lot of people get ridi of perfectly good sheets when they change their decor. Check your thrift stores and I bet you will find them.

I just bought some at Target. They have deep pockets and an extra wide elastic. Great sheets and I think the King were about $60., I bought 2 sets they are so nice, they come in a cloth mini pillow case

the quick solution to sheets that are a bit too large is to add elastic to the edges. Most only have elastic in the corners. the second solution is to buy only flat sheets and make your own fitted sheets adding elastic all around. I have been making my own fitted sheets for over 46 years as I started with my first child, when we were broke and had to make do!!! Number 3, You can also add pockets to the corners. Number 4, There is also corner holders that look like wide elastic with a clip of some sort on each end(need sets 0f 4), then attach one a set to each side about 10 inches from the corners. Best of luck with your search.

Linen-N-Things may have some, they have an online store too. Also catalogs such as Lillian Vernon and Miles Kimball sometimes have a set of elastic to keep fitted sheets snug. They are a few inches long and each end has a clip-one clip on one side of the corner and then diagonally across the mattress corner to the other side of the same corner

put some elastic around the corners, stretching the elastic as you sew it on. :)
