This quilt can be made in rows or columns or 4 patches. I might make it in rows, not sure yet.

Use the pattern with the grids to know which way to turn your hst. I suggest crossing out any portion of the pattern as you complete it so you don’t repeat a row.

You can make the quilt exactly as shown in the pattern or you can cut the pattern to delete some rows and columns (that’s what I’ll be doing).

To make the pattern as shown, you need 192 half square triangles total, so you need 96 dark squares and 96 light squares.  One dark square and one light square make 2 half square triangles.

Here are some size options:

If you start with 8 inch squares, the finished size will be about 84 inches wide by 112 inches tall (long king size). You need about 4.5 yards of dark fabric and 4.5 yards of light fabric.

If you start with 6.5 inch squares, the finished size will be about 66 inches wide by 88 inches tall (full size). You need about 3 yards of dark fabric and 3 yards of light fabric.

If you start with 5 inch squares, the finished size will be about 48 inches wide by 64 inches tall (twin size).  You would need about 1.75 yards of dark fabric and 1.75 yards of light fabric.

If you start with 3.5 inch squares, the finished size will be about 30 inches wide by 40 inches tall (lap or baby size).  You would need about 1 yard of dark fabric and 1 yard of light fabric.

If these dimensions don’t work for you, you can delete rows or columns or add rows or columns as needed no matter what size squares you use.  Just remember, if you add rows or columns, be sure you keep the spiral pattern going.

Thank you for supporting my efforts to create these patterns!
