The magical thing about "found" objects is that when you find them it is totally by accident. You are walking along and, "hey", there it is! I have found myself actually scouring the ground for more. It just doesn't work that way. Thus the name found.
Isn't it a treat to discover a special treasure now and then? It does tend to make one more observant. Here is a picture of a little metal treasure box with one small collection of found objects. Someday these will find their way onto one of my art quilts.
