Kathy-
I have a grace frame set up and just extended it out to the king size.It is now 109 inches long and I have it along a wall with room in the back side and the front edge is 45" from the wall. There isn't enough room to work from the back side unless I pull it out a little further. I do all mine from the front so I can see better. I just do free motion. If you need to follow a pattern then you would be on the backside. Hope that helps. More? Let me know. :)
