Our color samples are meant to only show the color options of our products. The samples can be cut from different fabric momme/weights.
Our sheets and accessories come in a three weights, 19, 22 and 30 momme. The weight of the fabric is a bit difficult to get a true feel for from a small color sample cutting. This is why we now also have a Momme card option that has a 4" square piece of each momme included to get a better feel for the fabric.
Feel free to check out this blog that talks all about the differences as well:
