To explain these terms is
Nickel = 5in square
Dime = 10in square
Quarter = a quarter metre strip
Fat Quarter = cut a half metre along the fold
Therefore, from a fat quarter you can cut 12 nickels, or 2 dimes + 4 nickels, OR from a dime you can cut 4 nickels.
For the purposes of the quilt we are making (page 47 "Nickel Bricks") we are using the end of bolts from these two ranges. The colours work brilliantly as you can see from the attached image.
