Sunflower Wreath Says "Welcome"

A wreath with sunflowers is sure to say "Welcome" to guests. The one shown in this post is on the front door of a sister's lovely home. It is cheerful and colorful in bright yellow. During the coming winter, there will be no sunflowers nor too many sunny days. So in these precious autumn days, it's nice to have both. Sunflowers are quite cheerful and can help make humans cheerful, too!
