You can increase the flower size by adding more rounds and adjusting the stitch count. Remember to maintain the pattern of increases to keep the flower flat. Specifically, Row 4: Alternate 1 sc, 1 sc inc around that row for a total of 54 stitches. So, one single crochet in the first stitch, two single crochets in the second stitch, one single crochet in the third, and two in the fourth, etc... Then, Row 5: SL in the same stitch that ended the last row. DC in the 2nd stitch from the hook. SL, DC repeat around. SL to close. Cut the thread with enough to weave in the end. (36 stitches)
