Throughout all of these forums, it seems we all have an opinion on whether to pre-wash or not. Personally (and ONLY personally) I prefer to pre-wash everything I buy. It doesn't take long and I always do it in cold water. There are several reasons:
1. It removes any chemicals used in the manufacturing process.
2. If the fabric's dyes are not stable, it will remove at least most of the dye that would come out when you washed the quilt -- preventing the dye from running into the fabric next to it when it is washed.
3. I can iron everything and fold it the way I want, because I fold it a special way and can then cut a piece off the whole thing without unfolding everything.
4. I find that the fabric 'feels' differently after washing and then I know how it will incorporate into the quilt and 'play' with the other fabrics.
5. If the fabric is going to shrink, it does it when I wash and iron it.
6. It makes me feel safer in my quilting because of all 5 above.
Now, I know that not everyone pre-washes. I'm sure thier quilts are wonderful, beautiful and a lovely part of their lives. I have also heard that for quilts that will be used on a bed, pre-washing is necessary, but if you are making a wall-hanging, pre-washing is not necessary. -- So, many opinions and thoughts. Just wanted to share mine.
