    I knew I saw this done on here and did a search. I came up with two links to John Flynn's site but I come up with "page not found."

    I bought 3 yards of flannel for backing but when I washed and dryed it, it came out to be an inch short!!!!! I remembered something about the Flynn method but now can't find it.

    All help is definitely appreciated!!

    Ah ha!! I felt so silly asking when I couldn't find it thru our site's search function! Thank you for your help.

    Now to figure out that formula - do I remember algebra???

    I'm going to try the calculator now to do the math. Something isn't adding up. I used the figure I got, plotted it out on paper, made the diagonal cut on the paper, and it doesn't work out. One more time. It looks so easy - once you get the right number!!!

    if you only need a few inches yo don't have to slide down very far, i haven't figured out how to do the math but i make my cut and slide and measure till it's wide enough and long enough.
    this meathos makes it so much better for quilting on a frame because it distributes the seam across the whole back enstead of right down the center

    I try to avoid diagonal sewing on anything whenever possible. I don't like how the bias seams never seem to lay as flat as straight of grain. I prefer the extra wide backing fabric or lengthwise piecing or scrap/leftover backs.

    Well, I got the math done and played with it on paper to see that it works and it does!! You do have to pin that seam a lot and then when you press it, you PRESS it and not iron it. The sandwich has been made! All I have to do yet is wind the bobbin and then I am off!!

    Would love to hear how it works out & to see the quilt when done.

    Well, this might be a double post! Sorry! But here are pictures of the Cinderella quilt I made for my granddaughter. I took the picture of the back looking in to the sun and the diagonal piecing line showed up well.

    Just wanted to relate my experience as a "lefty". When working it out on graph paper I originally drew my diagonal line from top right to bottom left. When cut it makes it longer but skinnier. Then did it top left to bottom right which gave me the wider I needed. Didn't even think about the fact I might be doing the "lefty reversal" so Lefties look carefully before you cut!

    Here's another web site that does all the math for you, all you have to do is plug in your numbers:

    http://www.multi-patch.com/html/diag...calculator.php

    Much easier than trying to do the math yourself!
    I made a royal mess the first time I tried this, thank fully it was on a scrap piece of fabric, but it's work out fine since then for me.

    Great quilt!! I use the diagonal seam for smaller quilts and don't seem to have any problems. I do starch before I cut the diagonal, however, and that seems to keep stretching to a minimum. For larger quilts, I like the wide fabric.

    Try fusing a strip of lightweight INTERFACING to the diagonal line before cutting.
