Hi Tom, SORRY for your problems. Yes cotton does shrink, it can shrink from such a small amount that it doesn't matter or it can shrink inches. We've all had this happen at some point in time. I know that your heavier weight tighter weave cottons don't shrink as much as your lighter weight looser weave. Most of the time at the larger fabric (the big chains), and hobby stores have the biggest problems with shrinkage on the "big sale fabrics". I bought them because I liked the print or the color, but I know that I'm going to have to deal with shrinkage. So if I need to end up with X amount, then I know from past experience to purchase I make it double the amount I need just in case I have a lot of shrinkage. Any that is left over can be used in something else, as it has already shrunk. Good luck
