This is a real quilt block, meaning it has batting and is machine-quilted before appliqueing on the sweatshirt, so will add to the warmth. The shirt is a Ladies Large Hanes Sweatshirt in a teal color. ****BTW, The teal block color matches the sweatshirt better than the picture looks-must have been the flash of the camera. Cold weather is coming, ladies! Payment by postal or bank money order only. Ships when payment received. Thanks.
