If you want the pieces that go right along the top of the door ( between door skin and glass ) they are called window felts. Wild Horses has them on page 90 of their newest catalog part # 9026 they are $30 pr. ( one door ). If you want the pieces that go up the side and across the top , they are window frame felt and are $25 per door and are also on page 90.
Tom's has them on page 17 and they are $59 and $39
