Renata,
I think you are right on with the binding. I would add a little more just in case you might want to make it on the biais, then you could have a little waste there.
As for the border strip, I think it is 1" wide too. I was able to design most of the quilt in EQ7, with the center block being 18", nine-patches are 3", the bigger blocks are all designed with thirds, so I hope they are 9" or else!, with that border made with 1" squares, this leaves probably 5" for the vine appliqué background, 9" for the top and bottom appliqué border (heart and fence) and 4" for the last border with flying geese. I get the size of the quilt at the charcoal border to be 56" x 76", so this would mean (56+76) x 2 = 264 plus the seam allowances. I agree with your calculations of 7 strips X 1-1/2 wide.
Renata's calculations are accurate, I would add a few inches more, just in case....
Well, I suppose the piecing can finally start for me! After much deliberation and taking photos of fabric combinations, loving them one day and hating them the next, I have finally stumbled on a combo of fabrics from my stash that I will feel comfortable starting this BOM with. I liked some features from Lynette Anderson's other quilts, so I'll be putting two birds instead of one on the roof (unless I end up with shi-shi dogs from Okinawa...) and since this will be a Christmas quilt, I'm almost sure I'll be embroidering trunks and branches of what will be Christmas trees in front of the house, instead of applique work on the trees . Hope I don't change my mind again...
