I have a more expensive Kenmore I just love that is very similar, so I bought this as a second sewing machine. It has surpassed my expectations. I have sewn different weights of fabric and have used different types of thread, without any problems what so ever. I've made some baby quilts, bags and flannel pajamas and feel I have given it a real workout. I purchased a Brother sewing machine from overstock previously that I should have returned since it had a problem with the tension control that could not be fixed:( The Brother machine is made so cheaply when you compare it with the Janome brand. Take my advice, buy the Janome and stay away from Brother!
