[QUOTE=terlyn;6621302]I've learned so much from the questions ive posted here before.
Now...I cannot find any 108" wide backing fabric to match so I will have to piece tieback.
Do I make my joining seam vertically down the back or the seam across horizontally?

I was told years ago not to have a seam in the middle - it's where we generally fold them and it weakens over time. If I am joining two pieces of fabric, I cut one length in half and join on both ends - no middle seam. I think backs are fair game, no rules really, just add where you can and avoid the middle seam.
