These pads are sewn to last. They don’t have that hot-off-the-assembly-line look, but they are durable. I use polyester thread (the one ingredient that I buy new). My grandma's old Kenmore doesn't do anything fancy, but it does a good job. The flannels are sturdy – many of them are from those work shirts that last for years and years. The flat cotton is the stuff that’s usually used in quilts, and the terry is from commercial kitchen towels.
