Has anyone else done the math for 12 blocks? Just curious if I am doing something wrong.
I calculated the amounts and get different from you. Here is my math. Bear in mind that I do my calculations based on WOF as being 40 inches wide after washing (may be 42 or so, but I am being slightly conservative)
I am using the colors as what I used, the only one you need to keep as mine is the center - black
Color 1 (black - center) 1/2 yd with 4 inches WOF (width of fabric) left over. You will need 12 squares total. You will get 6 blocks per row, you need 2 rows. You will only need 13 inches of fabric, but unless you can get the shop to cut you 1/4 yard plus another 5 inches - you will end up purchasing a 1/2 yard.
Color 2 (my red/orange floral) 1 yard. Since you are cutting both 3-1/2 and 3-7/8 inch squares, I based the measurements at 4 inch squares. You will need to cut 48 3-1/2 inch squares and 24 3-7/8 inch squares...making a total of 72 squares. You will get 10 squares per row. You will need to cut 8 rows. 8 rows of 4 inches per row =32 inches total = 1 yard.
Color 3 (my orange rectangle) 1 yard. You will need to cut 48 rectangles. I calculated it two ways. First, cutting the strips at 3-1/2 wide then into 6-1/2 long, you will get 6 rectangles per row. You need to cut 8 rows. 8 rows of 3-1/2 inches =28 which make the amount needed 1 yard.
Color 4 (my beige) 1-1/2 yard. You will need to cut 24 3-7/8 squares and 96 3-1/2 inch squares...a total of 120 squares. Again, basing the squares at 4 inches (always allow for a little leeway when cutting) you will get 10 blocks per row. You need 12 rows. 12 rows at 4 inches wide=48". 48-36 (1 yard) is 12 which is 1/3 yd, but I would rather have a little extra. So instead of purchasing 1-1/3 yd, I would purchase 1-1/2.
So - the totals I come up with are as follows:
Color 1 =1/2 yard (or you could actually get by with 2 FQ's
Color 2 = 1 yard
Color 3 = 1 yard
Color 4 = 1-1/2 yard
It does seem like more fabric - remember that the other blocks were only squares. This has flying geese and corner triangles on the blocks which cause wasted fabric when you cut the corners.
