The first thing I do, is sort my scraps into piles by size. The easiest to work with are strips. These I iron, sort by approximate width, and stack 6 strips high, aligning the top and right side edges. Then I cut each stack of 6 strips to exactly 2" wide by slightly more than 14" long. From each one of the strips, I will get one set of petals and one center. After cutting 5 stacks of strips (a total of 30 different fabrics), line them up next to each other as shown above, and cross-cut 2" squares through all of the strip piles at once.
Now, pick up the piles of 2" squares, and place them in stacks, alternating the orientation as shown above.
Next, use dressmaker's shears to trim the corners off of each of the piles. Each pile has 6 fabrics, so you are trimming 6 at a time. Re-stack them as shown above. Note that there are only 6 piles in each row. The 7th pile in each stack, I have set aside to use for centers. These I keep separate from the petal sets, selecting a center for each petal set later in the flower-making process.
The final step is to separate each of the piles into 6 separate piles, one for each of the fabrics. You will end up with 30 singles piles, or petal sets, each with 6 of the same cut and corner-trimmed fabric, enough to make 30 hexie flowers.
Certainly there are other, and even possibly more efficient ways to cut fabrics for hexies, but this way works well for me. Some quilters recommend using the squares without trimming the corners. I tried it that way, but went back to corner-trimming because I like not having the extra bulk toward the centers of each hexie. I'm especially glad I trimmed the corners on my Grandmother's Flower Garden hexie quilt, because it was that much less to stitch through in the hand-quilting process.
Sometimes, the fabric scraps are not strips, or would more effectively be cut as a chunk rather than strip. Basically it's the same process. I stack 6 different fabrics, aligning the top and right hand edges. From this stack, I cut a 4 x 6 inch block, and then cut that in half to make two 2 x 6 inch strips. I align the strips the same way as the 14" strips above, cross-cutting several at one time, and finish the same way as described above.

A very handy, and more complete cutting guide is available from Paper Pieces, which is where I get my pieces. Nope, I don't cut my own; too boring, and I really like the precision of die-cut paper pieces!
