For a 30½" square quilt made with a charm pack:
Birdhouse block size: 4¾" x 4¾" finished
Sashing strips: 1" x 4¾" finished (cut 1½" x 5¼")
Cornerstones: 1" x 1" finished (cut 1½" x 1½")
Inner border: 1" wide finished (cut 2 - 1½" x 22½" and 2 - 1½" x 24½")
HST border: 3" x 3" HSTs finished (make in the same manner described in the tutorial using 4" squares to start - you'll have to trim the charm squares first)
Outer border corner squares: 3" x 3" finished (cut 3½" x 3½")
I plugged this larger design into EQ7 and it's looks like you'd need roughly a yard of background fabric and ½ yard of fabric for the birdhouse roofs.
Here's a link to a foundation pattern that I drafted for the 4¾" birdhouse block. And here, again, is the link to the original tutorial — the cutting measurements are different for the larger quilt, but the construction is the same.
I'd love to see what a bigger version of this quilt looks like and I may even try one myself! One reader suggested appliquéing a black circle to the larger birdhouses rather than using buttons — great idea Cheryl!
