I have gone so far off route, I am not even vaguely pretending to be doing it now....
I had planned to get a longarmer to baste my Di Ford Mystery Quilt for me, but she didn't have any water soluble thread and said it would take 10-12 days for it to arrive so I pin basted it myself.
I centred the backing fabric on the table. I then placed the cotton batt folded in half on the same centre line, then opened it out. Here you can see how I did it with the wool batt which is going on top of the cotton one. My kitchen table is 6 foot by 3 foot but this system would work equally well on a smaller table. However I would love a table with straight uncomplicated edges to grip onto.
I love the fabric I have chosen for the back of the quilt.
