Just FYI the Easy weed Extra from Sisner is great for poly to nylon, will not work on cotton at all. I use it on bags works great light pressure (70) on gx24 and slow speed 5-10 per second. 15 seconds is about right, if sits on top material, reheat press with Teflon and little more pressure. usually light pressure on heat press for this. pillows help with this also.
