When selecting your fabrics try to stick to the same weight and type of material. I found after cutting my squares that the pink butterfly fabric was too heavy or bulky with the other fabrics and had to make a trip back to the fabric store to choose another material. Also make sure your fabrics are machine washable to avoid dry cleaning bills on such a large item.
Wash, dry and iron all fabrics to eliminate the possibility of shrinkage after your quilt is finished.
Cut 33 squares of fabrics 1 through 5 and 34 squares of fabric 6.
Once your quilt squares are cut lay them side by side plain, pattern, plain (or vice versa) to determine how you want your pattern to work out. The last color will be the most prominent on the quilt. Once you have decided how you want your pieces to lay in the design assign each fabric a number from 1 to 6 and set them in order on the table so you only have to move down the line when you pick them up from the pile as they are added to your quilt.
*Note: If you have access to a serger and a rotary cutter and mat I highly recommend using them as it will save 2/3 of the time you will spend cutting squares with scissors, trimming and pressing seams open during the assembly of your quilt and will provide more uniform squares.
If you must cut your squares by hand pinking shears are your best choice to prevent raveling because of heavy handling and will reduce raised or lumpy areas under your seams.
