I simply think it would be far more practical to do this sort of routine once and be done with it in that doing a repetitive routine at each table not only gets boring for the performer, it destroys the element of surprise and wonder not to mention, risks exposure. YOU NEVER REPEAT AN EFFECT unless you have several alternative methods that can replicate it.
I think the OP is just too short on time to pull this together for this season but should consider the challenge and make the investment on materials, such as a himber ring and similar bits that can be made intimate and carry the Valentine message if he wants to stroll at an event doing theme appropriate routines. There used to be a Rose on the market that worked similar to Ring Flight in which a vanished ring ended up inside the bud of the rose, Copperfield did it on one of his specials some years back and it kills. Depending on your slight of hand skills you can create a Snow Storm effect using the petals of a flower (but not at an event where food & drinks are being served. In such cases save this for the stage)
Get creative and cut your own sponge pieces into hearts and do a modified sponge ball sequence. . . we could go down a long list when it comes to modifying known props let alone patter that can tie into this or most any other theme. The point is, it takes time to pull such things together, especially if you want quality in your end product.
