How to make sheets fit if mattress is not tall as sheet pockets?

Sheet straps! Sold almost everywhere or on line.

There are these elastic bands that clip on the corners come under different names, sheet suspenders. Sheet clips, sheet straps...

Use sheet straps (look like old fashioned garters used to hold up stockings). Make sure they are metal fasteners rather than plastic as they are easier to attach & hold much better. Walmart & Bed, Bath & Beyond carry them as I’m sure other bedding stores would too. Clip one end 12-18 inches from the top corner at/on the head of the bed part of the sheet & attach the other end that same distance on the side of the sheet. Do the other top corner then do the corners at the foot if the bed. Have been us8ng these for years & the sheets stay on the bed.

Hi there. Cindy here. If you sew (by machine or by hand) elastic strips on to the corners of your sheets, they will hold the sheets in place. They will keep the corners under your mattress. I hope this helps you. Good luck.

You can attach elastic on the corners. Attach about 3 to 4 inches down from the corner on each side. That way it will pull your corners down and should tighten up your sheet.

Thank you so much for the info
