Made a queen size quilt and machine quilted it on my Singer, sitting on the kitchen table. Just rolled the sides up, started from the middle and worked out from there. Don't know if it was beginners luck, but there were no puckers on the back. I did have it pinned a good amount. Think if I ever make another one that big I'll baste instead of all those safety pins. Just can't afford or justify the cost of sending a quilt out to be quilted.
