Tips: Keep in mind when ordering glass or fabric lamp shades that each batch of fabric and glass is different. An item may look identical to one you have, but there will be subtle differences. For fabrics each dye lot will be different. For glass shade each mold will be slightly idfferent. An item ordered one month may be slightly different the next month because each mold or dye lot is different. If you are trying to match an item you already have it is better to replace all itemsm if possible if an identical match is desired. If matching items will not be right next to each other this may not be a consideration.
