I felt my wreath needed more foliage and looked unfinished or slightly naked without, so it was time for a faux-leaf run. As mentioned earlier, I stopped by the Dollar Tree a few weeks after buying my original supplies in early September, and they were basically sold out. I was in luck during a quick visit to my local Michael's (an arts and crafts retailer) -- fall faux foliage was more than half off. It was there that I picked up the faux grass, which I thought would look nice on the outer edges of my fall wreath. About five more bunches of foliage, and I was ready to tackle the project again.
Lesson learned: Buy more rather than fewer wreath decorations, especially at stores that carry seasonal items on a limited basis. You can always return what's left over, or use it for another project.
