This is a stain glass piece that my sister Lynda made for me. It is called a Celtic Trinity Knot. She started doing stainglass a few years ago but put it aside for a while and then just recently she got back to doing it again. She has made a few large pieces and seems to enjoy it. It is certianly a beautiful hobby, a lot like quilting, because you are designing and making something of your own creation. Nice work Lynda.
