My mom bought a bunch of Betty Crocker kitchen utensils (spatula, scissors, cheese grater) actually at Dollar Tree. Her initial thought was bookmarks purchased online, but just happend to stumble upon the Betty Crocker stuff that ended up being cheaper b/c didn't have to factor in shipping and handling.
Oh.. I just realized you said 'garden theme' favors. I missed that part. Sorry! Mine won't be as useful. But maybe still check out Dollar Tree for little pots/flower seeds, or garden utensils, or windchimes, etc?
