Write the "TO" and "FROM" names supplied in the order email on a delivery booklet. Time to show off your nice handwriting! Make sure you use the display names specified for the delivery card, and not their real names.
Punch a hole in the top corner of the delivery booklet.
Pick your flowers as specified in the order and trim them down to about six inches, removing leaves and thorns. Remember, the customer will be counting blossoms, not stems, so e.g. a lily may need to have extra heads trimmed off.
Wrap the flowers carefully in cellophane and fill with water...
...and close firmly with a twist tie or rubber band, making sure the stems are in the water and the blooms are sitting happily together.
Scrunch up tissue paper into a sausage shape and wrap it firmly round the bottom of the stems.
Envelop the whole thing in brown paper...
...and tie tightly around the waist with several neat turns of craft wire. The posy should be flat bottomed and free-standing.
Trim excess paper so the blossoms are nicely framed, and can all be easily seen.
Attach the delivery booklet using the end of the wire.
And you're done! Double check that the flowers are exactly the same as in the order, and they are easy to distinguish for the recipient to decode.
