I wish I could have attended a seminar from Marti about this technique but it was not to be. Sew, with book in hand, on graph paper, I carefully planned my attack of dividing the bed size quilt tops into manageable pieces that would allow me to stitch them together after quilting. Marti provides 5 methods for working in sections so planning is a must. For my first project I chose not to use the seam strips. Instead I quilted to within one inch of the outside of each section and joined a five layer seam, leaving one of the backing pieces to press, fold over the large seam and then sew down over the seam to hide it.
There are 3 large tops that I had near completion: a mystery quilt from the sewing center that went together very easily (due to the big pieces), a scrappy pinwheel quilt, and a 90x100 BOM that I plan to back in flannel. The mystery was done first, and since it was not one of my favorite projects (DH asked with a frown in his brow if I planned to keep it), it became the guinea pig. The scrappy pinwheel still has blocks to finish and the BOM had to wait until a test subject had been
The part of quilting that I dislike most is sandwiching, especially large pieces. This method helps immensely. My largest piece was 45x45. Yes, I cut more backing but it was so much easier to get the small sizes ready than to work with one enormous piece, same for the batting.
I am sorry there are no photos in this post - blogger is not cooperating! I will try later.
