measurements for a filmstrip quilt

I've had some requests for a tutorial on the filmstrip quilt, so here goes....

The filmstrip quilt is made of two different blocks. For block A:

Start with a 5" square of a colored fabric.

Cut 2 pieces 2.5" x 5" of white fabric. Sew to the center square using 1/4" seam allowance. Press.

Cut 2 pieces 2.5" x 9" of white fabric. Sew to the top and bottom of the block. Press seams well.

Square up the block to 9" if necessary.

For block B:

Make the blocks the same as above, but in the reverse. Start with a 5" square of white fabric, surrounded by a 2.5" colored border.

To make a baby size quilt, the fabric requirements are as follows:

1.5 yards of white fabric

1.5 yards of assorted prints

Make 15 A Blocks and 15 B blocks. The layout will be 5 blocks wide and 6 rows long.

The quilt will measure 42.5" x 51."

For the larger version the fabric requirements are:
40 charm squares (5" squares)

1 jelly roll (or 40 strips 2.5" x width of fabric)

3 yards of white fabric

For this size, you will need to make 80 blocks. 40 A blocks and 40 B blocks. The layout will be 8 blocks wide and 10 blocks long.

(shown horizontal)

The finished size of the quilt will be 68" x 85".

If you make a filmstrip quilt, I'd love to see it!
