Thanks for that Moonpi. :D
KLue, I didn't want to have horizontal seams on the back because when I experimented holding up a QAYG I made before, it doesn't hang right with the seams crosswise, although lengthwise is fine.
Dunster, what you suggest is what I was considering. If I SITD, obviously I'll have to do the seams I join after I'd joined. And if I did echo, how close to the edge of the sections could I go and still leave enough room to manoevre when joining?
Thanks everyone for helping (and Terri for liking it!) sorry to be a pain, I have no experience of machining such a big quilt and I don't want to hand quilt it - that door needs covering THIS winter! :lol:
