Select a silk arch for over a doorway based on the decor of the room in which the piece will be displayed. You can choose silk colors that match or complement the existing room decor. If the piece is over an open doorway, make sure it coordinates with the room or hallway beyond as well. .
Select special silk arch wreaths for the holidays, using traditional color schemes. Choose red, green and gold for Christmas, black and orange for Halloween and light pastels for Easter. If you use an everyday silk piece over the doorway, you can replace it for the holidays with a specialty wreath, and create a festive display in seconds. You can also create or purchase arches for holidays throughout the year, and simply swap one for the next as the months progress.
Depending on the type of silk arch you're using for your doorway, you can hang it with a picture hanger or temporary adhesive hook. If you're planning on using the wreath for a single holiday, then hang iwith a temporary adhesive; you can display the wreath over the door without damaging the wall surface. Arches you plan on using for a longer time period can use a more permanent method -- a pair of picture hangers can display the arch securely until you decide to remove it. Check the arch before you mount it over the doorway; a vigorous shake will remove any loose petals that might otherwise fall on people as they walk by.
Most silk flower arch wreaths require little to no care. Choose a doorway that is out of direct sunlight if you plan on using your silk flower arrangement for a long time; faux florals can fade with prolonged sun exposure. Use a hand vacuum or the attachment on your regular vacuum cleaner to remove dust from your silk doorway arch as needed. The canned air used to clean sewing machines and computers will also do the job.
