This star chart is the coolest when seen with the lights off since it has a lot of glow-in-the-dark action. The repeat along the length of selvage is 36" and across the width approx. 36". And reading the names of the constellations is endlessly entertaining.
You can see in the second photo how the fabrics in the collection relate to each other in scale except for the large 36" by 42" Solar System Panel which just did not fit in the photo..
How much fabric?
