A few years back I purchased a plain grapevine wreath from Micheal's (I believe I only paid 2.99 for it). This week I purchased one fall leaf spray from Walmart for $3.00. The only other supplies I used were wire cutters and a brown ribbon I had on hand.
I took the fall leaves and wove them into the grapevine wreath, taking time to space them and make them sit with the right side up (as much as possible). One could use wire to hold them in place, or a glue gun. I didn't see a need for it.
.....et Voila! 40 minutes later, a beautiful wreath for my front door. This could be made for any season - think flowers (Christmas, spring, summer...). Just let your creative juices flow!
