I own a custom wedding invitation business,but one of the retailers I know and occasionally work with,The Linen Closet,is available to do this. She deals in only upmarket,quality linens,and might be a good choice for you. It's called the Linen Closet in Delray Beach,Fla. She has a simple website. If you need further help,you can reach me through my own website www.invitationimagination.com
I have linen rental packages that I offer to vendors in my " Vendor Incentive Program" . We are an event planning/design firm but we also do rentals such as chair covers, sashes, ostrich feather centerpieces and linen. I have 2 linen packages that you can offer your brides. Visit us at www.puredymondsevents.com and fill out the vendor form and let me know what you need.
