As usual,my camera doesn't do justice to the colors.May be some day I'll get a better one.
All are different variations of wheat ear,except for the base and stem of the blue flower.
For the top curve from the left hand side I've done detached wheat ear,Elizabeth's variation of wheat ear (if you pull it too tight the cloth puckers ),wheat ear type 1,wheat ear type 2 and the variations in detached wheat ear.
These are the my sources of info about wheatear
