Custom Made Flat Sheet of Superslick Acetate Bridal Satin. Only 100% Acetate has this super slick feeling that is unique to acetate satin. [Custom Made Flat Sheet of Superslick Acetate Bridal Satin for a 12” Mattress standard size. Center seamed. Please note that acetate is not a truly washable satin. Usable life can vary especially with the bottom sheet and pillowcases. Discounts are not applicable to custom-made orders. The Fitted Foot option on the Top Sheet is an extra section, on the bottom edge, that reaches from corner to corner, where we put in an elastic edge in the corner only. This makes a long pocket or Fitted Foot that is like the corners of a Bottom Sheet. There is no elastic along the length of the foot so your Top Sheet will not bunch up at the bottom. This portion is to be tucked in between the mattress and the box spring just like the Bottom Sheet. Now your Top Sheet is secured to the mattress and there is less of a chance that it will slip off during the night! Click on Images to view Colors Please allow 2-3 weeks to ship.
