Several months ago, my husband, dropped this 'beauty' in my lap. I did what any self-respecting woman would do - I jumped! Then I looked at it and realized that it was just little threads all crammed together. It came out of one of his customer's washer's drain hoses. She had just completed a rag quilt and did the necessary washing to make it fuzz up. She called us to come out because for some reason her washer wasn't draining. After much checking of washer parts and finding no problem, Larry found this clog in her drain hose.
Most of the directions for rag quilts include the admonishment to check your dryer lint screen several times during the drying process but they don't warn you that larger pieces of thread can get into your washer and clog the drain hose, or worse yet, get knotted in your drain pump.
Now most of us don't admit to our spouses the actual amount we spend on fabric but it is really hard to hide the bill from the appliance repairman! So this is just a friendly warning to anyone making a rag quilt - GO TO THE LAUNDROMAT!!!!
