Outdoor Wedding Ceremony Decorations

I need to create an outdoor setting two days before the ceremony - mainly in tulle and ribbons for the arbor, deck railings and EZ up tent. Just curious to know if the slight rain after the introduction, how tulle / ribbon react? Should I consider spraying with a water repellent spray? Any use of tape spray icing - seen in a craft store. Any thoughts and ideas.

light rain and tulle are not enemies. dries. because it is woven mesh and it will not show any traces of water when it dries
.. Tape according to color and matterial could show water spots, but if the rain covers the entire colon tape dries out and does not show.

Do you know that the tape is made?

I do not spray repellent unless you test a sample to make sure it does not do whicky ribbon or funky gunky

It will not matter if you spray it --- Flaten. If you use colored tape, the dye can bleed on the tulle. The best thing to do for you is to bring the arbor and railing, then cover with plastic.

Waterproof poly ribbon can help. You can check this site and http://desbijoux.com. They have nice arches that give you some ideas.
