Also check out wreath makers on Etsy.

Once you find a look you like, you can use a wreath frame like this to build your creation. Plenty of inspiration here too!

Thanks so much!!!

There are few flowers which are durable for any length of time after drying - sadly roses are not one of them.

Spray with hair spray and they last longer. If they fade retouch with a light pink water base craft paint. Your wreath sounds beautiful, Oh, and add some faux greenery for color and a bow.
