I don't have the exact measurements for too much, as I basically wing it when I make them.
Sorry, I didn't measure these circles, but they are placed on 9" by 12" colored construction paper, so you can estimate the size by comparing it to the paper. They don't have to be exact.
Cuts already made. Randomly take something round like a marker and curl the strips of paper on the marker. See a close up of the finished flower up above to see what I mean. (biggify the photo)
The folds that are made on each petal are made on the edge of a ruler randomly, radiating out from the imaginary center of an imaginary circle. (Clear as mud......) Some folds are done from one side of the paper and some are done from the other side, in no apparent order and no rhyme or reason.
