Store them in the right placeMany people often store their table linens in their attic, basement, or garage, and that's really not ideal. Those damp and dark places are a breeding ground for mold, mildew, moths, and other conditions that can ruin your linens. Closed containers are also not ideal because they can trap in moisture. Keep your napkins, tablecloths, and skirts somewhere dry and room temperature. A closet would be perfect.
Always use table skirt hangersSpeaking of a closet, how are you going to store those puppies without any hangers? You want to make sure your linens look their best before the wedding and putting them up on table skirt hangers is really your best option. Not only will they stay dry and safe from mold in your closet, they are also less prone to wrinkles compared to being shoved in a tote deep in your basement.
See if they need dry cleaningA few weeks before the wedding, you should pull out your linens to see if they need dry cleaning. You really should have them cleaned before you put them into storage, but you never know if something happened to them from the last time they were used. Don't wait until the last minute to get this done either. There might be a hold-up at the dry cleaners and you don't want guest table number five to see that huge yellow stain.
Steam them before the weddingAfter you inspect them, you'll know whether or not they need to be steamed. If you take them to the dry cleaners, they will probably steam them for you. If you don't, it's probably best to take a portable steamer right to your wedding venue and steam the tablecloths and skirts after you dress the tables. That way they are set in place and look great for the reception.
Your wedding linens really make or break the aesthetic of your wedding, so make sure you take care of them. After all, you never know when you're going to need to use them again!
