I have a small ironing board I lay across the arms of a chair and have it next to my sewing machine for the smaller projects or blocks, but get up and go to the big ironing board for the larger things, just so I move around a bit.
But the tv tray sounds like a great idea too. Will have to watch the garage sales for an older one and fix it up to have on hand as well. Thanks for the great idea. the machine lady
