I found this forum about 3 years and 40 quilts ago. I have always found interesting info, and lots of friendly advice. There are so many quilters who have talent and perseverance (to me, this is a great part of quilting!) and don't keep the good finds and good ideas secret. I never prewash. In fact, I tell the recipients of the flannel quilts I make, that I recommend dry cleaning, if at all possible. And sparingly. Most of my quilts are either going to adults or babies. (Those, of course, are totally washable.)Don't hesitate to ask questions. That's how you learn. And welcome!
