So glad it worked for you, you made the right decisions for the scale of your project.
Sometimes I can get by with really close tolerances, the top I'm currently working on only had about an extra inch side to side on the batting but I did have plenty of the back for this one. Many of us have had the experience of somehow finding ourselves (too late!) an inch or two short on a long quilt... there are some creative solutions to that problem. Some pretty creative use of language too, but not fit to print!
