These flowers always remind me of a pantomime dame! The sugar example on the left (Yellow Delight) has been made slightly smaller than the veiners. This is done by cutting inside the impression left in the paste.
The wider of the two small veiners would normally form the top 3 petals of this orchid, but there are variations.
The photo on the right is of the real Miltoniopsis orchid these veiners were made from.
