Actual Size
Please note that rulers are not true to size, but are true in relationship to the item. This is because computer monitor resolutions vary widely, making it very difficult to create a true lifesize representation on screen. Please refer to the numerical dimensions specified for each piece for the most accurate information about sizing. Also please be aware that some minor size variation is normal for handmade pieces. See Measurements FAQ for more info.
