The Tumbler pieces were cut using the 6 1/2" AccuQuilt Tumbler die. I started with a fat quarter pack, but I can no longer remember what the total yardage was. The finished size of this one is about 40" by 40". So, I guess you could assume each piece is cut from a 7" square piece of fabric. If you had one yard of fabric, you'd get 5 strips of 7" times WOF. From each strip, you could cut 5 tumblers. So, that's 25 6 1/2" tumblers per yard. You'd need to do the match from there according to how many fabrics you want to use and the finished size you need. Hope that helps!
