KK, love your fabric choices and your work is lovely. The contrast between the bouquet and vase as well as the black/white pieced flower and red stem/leaves is outstanding. Incidentally, the bouquet treatment is called broderie purse wherein you cut out a floral print and applique it. Most often cut out one flower at a time.
May I suggest that next time you oversize your background blocks and then cut to the correct size once the applique is completed. If you look closely at your blocks, you have a very very small seam allowance at the the bottom of your blocks which may end up in the seam which is really a shame as your handwork is so beautiful. Perhaps you can loosen the bottom of the vase and stem and trim just a smidge in order not to cut off in the seam allowance.
No hard feelings here, please. We are all here to learn from one another and these are only suggestions. Suz
