I have made about 8 rag quilts.
I have only used batting in two, ones I made a dog quilts for last years secret santa. All the rest I either used denim and flannel with nothing in the middle (denim is very heavy). Or just a layer of flannel in the middle. If you do not use bating you will save time in the sewing. Flannel also adds to the ragged edge.
I cannot imagine snipping 5 quilts between now and Christmas. My hands hurt thinking of it.
A tip, if you have a top loading washing machine and have a soak cycle (that does not drain), use it. Strain the water with an wire strainer every few minutes. Keep repeating the agitating cycle. You will be amazed at how many thread bits you get out. Then complete the cycle and do as other shave said clean out the dryer screen every few minutes during the dry cycle.
If you are on septic I would not wash the quilt at home, the lint will clog the system.
I love rag quilts, but I would not make one for money.
