So now the search is in full swing for XL twin flat white sheets for VMI. I have seen on old posts that some people bought sheets at www.linensupplier.com. Have you been happy with these? Are they a decent quality? Do they seem like they will last for 4 years? We are at the point where we are going to have to buy complete sets, but I wanted to check this out first. BTW, "XL" seems to quite variable in lengths, depending on the brand. Does anyone know the minimum number of inches the sheets need to be to fit properly over their hay? Thanks!
