1.

Write the wishes, blessing, etc. ON the dollar (or whatever currency you are using).

Some things you could write on BLESSED Bucks:

May you BE BLESSED WITH JOY, LOVE, health and wealth.
Have a scrumptious day!
KEEP happy, healthy, wealthy and wise.

Abundance is yours.
BE WITH BENEVOLENT PEACE.
May your life BE EVER BLESSED.
BLESSED-BE.

BE-WITH-BENEVOLENT-PEACE.
GOLD-CLOUDS.
KEEP-GOLD-HEART.

BE-WITH-LOVE.
COUNT-WITH-JOY.
EMBRACE-LOVE.

2.

Fold it neatly, so the blessing is seen.

3.

Place it somewhere where it will be easily found by someone else.

4.

No waiting and watching to see who gets the BLESSED Buck.

5.

Don't  DROP BLESSED Bucks ON the ground. Purposefully place them where you "plant" them. Money dropped ON the ground is a message to the Universe that you don't CARE about money.

It is best that the recipient not know where it came from, and that you not know who received it.

You can plant them:
ON a bus
ON a shelf at a store
in a shopping basket

ON a stack of newspapers
ONa changing station in a restroom
anywhere people will easily FIND them
