I was given a table runner in swap. The threads were buried but after a few washings the quilting started to come loose. The buried threads had worked out. The were not knotted before burying. I had to redo the thread ends. I didn't mind because I liked the runner. I told the giver about it and she got upset.. Said I shouldn't have washed it in washing machine. I only told her so she would know about the problem but apparently she didn't want to know. LOL
