I saw this idea on a crafting blog and made one a little different. I made the bird from cotton muslin and the legs out of bent out paperclips. I had wee heart shaped wreaths on hand and that became the nest. Add a bit of greenery, a bow and a flower or two and you're done.
The little flower arrangement was made using a candle holder which I absentmindedly sat in cool water after it had been on low heat on the stove to melt the wax in order to clean it out. It cracked (ugh!) so it became a flower pot.
