Yes, that is a good thing....it will feel heavier, and have a softer "hand". If you take a piece of cheap flannel, you can hold it up to the light and actually see through it! A favorite website of mine for batiks is Hancock's of Paducah--not to be confused with Hancock Fabrics. I LOVE their huge selection of batiks, altho haven't purchased any flannels from them.
Have fun @ Expo!
