Here's a horror story about old, poor quality fabric. A friend asked me to make a quilt from a kit she had had for some time. When I took the fabric out of the packaging I discovered that the instructions read "1980." It was so old the instructions did not refer to rotary cutting but drawing your cutting lines on your fabric. The pieces looked as if they were made of muslin, they were so thin. The largest piece was black and had been folded. When I opened it up the sharp edges on the folds all split and the fabric just disintegrated. I ended up with black dust all over my clothes, had to replace my ironing board cover, and had to mop my floor twice to get all the black off of the floor. Moral of the story - if you have any doubts about the quality, don't use it. Your time is too valuable to waste on poor quality.
