I have an old quilt that I made about 52 years ago. The seams are now coming apart, however it has been used hard and it has good reason to fall apart. In those days I used cheap thread and fabric and if it lasted that long, it has done all I could ask. I will not mend it, but it still is a dandy for kids to play on in the yard or on the floor or to make a "tent" out of, so I'll keep it for a while yet. How long should we expect our work to last?? If I make quilts now, I won't be here to see them if they fall apart so that's freedom from worry for me! Make them and love them and don't sweat the small stuff!
