I have purchased these sheets in various sets and single pieces 4 times now. I have a twin sheet set in the lavender. I have a fitted queen sheet in dark grey. More recently I bought the aqua twin flat sheet, and didn't realize until it was too late that they actually sent a King!!! Normally I'd take no issue with getting something bigger than what I ordered at the same price, but... I wanted the aqua twin sheet to go with my lavender twin sheet to make a "sheet quilt" because I need a cooling blanket of natural fibers. But imagine my surprise when I started pinning the sides together and the aqua one (which is more sage green) is twice the size of my OG lavender twin sheet!!! I'll keep it and make something else out of it, or just to have a spare in the summer, but still annoying for my particular project. I've since ordered a Caribbean blue flat twin sheet (which is the color I originally wanted, but was twice the price as the sage green "aqua"), and really hope I receive the correct size this time, because if not, I'll have to buy bigger batting!!! And of course, I had to buy natural ($.$) batting made of silk, eucalyptus, bamboo and cotton so it would be light and breathable. Anyways, if you're buying separate pieces, especially in a fitted sheet, make sure you got the right size before the return window expires! As a sheet SET, zero issues. And the single fitted sheet I got was also correct. I'm hoping this is just a fluke, because these are the most affordable eucalyptus sheets I've been able to find, and I absolutely love them!!!***They truly are COOLING sheets! This was my first summer with the fitted and flat sheets both on my bed, in northern Minnesota with the AC running, and my feet were actually too cold for comfort. So, silly as it may sound, my body maintains a normal temp, I no longer sweat from polyester/microfiber sheets, and I wear wool ski socks to bed. Don't fall for the hype of microfiber or cooling bedding made of nylon! Microfiber is always polyester, and both it and nylon are synthetic fibers that are essentially plastic, which does not breathe!!! Polyester is made from PET (polyethylene terephthalate) and nylon is made from synthetic polymers - BOTH made from petroleum! If you try to burn it, it will melt. The natural fibers bedding is made of are bamboo, cotton, eucalyptus, hemp, linen, tencel, silk and wool. LOTS of options! Anywho... as a person who truly runs HOT (must keep inside temp at 72° F or lower), natural beats synthetic any day of the week! And Tencel/lyocell (or eucalyptus) seem to be the coldest of the naturally derived fabrics for bedding, and it's more eco friendly than others. I also own silk, cotton and bamboo. My favorite 2 sets of sheets for summer are these and cotton percale. :)
