Take a red ribbon and tie it from a location near the front door of your apartment/house to various locations in the different rooms.  At each junction where the ribbon is tied, place a red rose. In all there should be 12 red roses.  The final location should be in the bedroom on the bed below the pillow and the 12th rose should have the engagement ring below the bud on the stem being supported by the leaves. Nearby should be a hand printed card which reads:

"Dear (Name)

12 roses - one for every month

Symbols of a precious love

Built on rock with smiles and tears

And ordained by God above.

Such a love is true and pure,

And stirs my heart to say to thee

Here, at last, on this great day -

Will you marry me!"
