I am new to sewing and I have been making fleece pants for my DS. As of yet all my fleece has been patterened and I could easily tell which side was the wrong/right side. Well, I have a small bit of MM fleece I bought off the TP. How do I tell which side is the right side vs. wrong side? I think it is 200W, but not sure. One side seems smoother than the other. Does it have anything to do with the selvage? TIA?
