you just have a block pattern? if so, first you need to determine the size of the quilt- *measurements* --- then divide length & width by the size of the block ( ie: quilt size = 80 x 90 ---- blocks = 10" you need 8 across, 9 down---or 72 blocks.) now list each fabric in the block and the size of each fabric- figuring 40" wide fabrics- divide the fabric (ie: fabric one = (4) 2 1/2" squares per block---{4 x 72 blocks = 288 2 1/2" squares} 40" wide fabric will let you cut (16) 2 1/2" squares- which means you need 18 *2 1/2"* strips to cut 288 squares....(18) 2 1/2" strips = 45" or 1 1/4 yard (36" + 9") ....so, that is the process...now you need to fill in your own measurements.
