I'm sure you'd be able to find a 3-bar cross or trefoil cross somewhere.
But, the reason I am posting this is because this hits upon an idea I've had for some time to serve as a fundraiser for parishes, schools, or youth groups: make stickers of St. Phanourios to put on TV remotes, car keys, pocket knives, etc.
If you're as absent minded as I am, you become very familiar with this saint, and he has interceded for me many, many times. I think it'd be a neat idea to get stickers made of this saint to put on these frequently lost objects, with the proceeds going to the parish or group selling them.
Just an idea....
With great respect, Father, is placing icon stickers on the objects you mention such a good idea? These holy images will be handled with often grubby hands, the remotes will be dropped behind couches, the car keys flung into all sorts of places, and any good and useful pocketknife will not stay pristine for long ... I even have a problem with icon stickers which are stuck to the clothing by church greeters of folks entering church on patronal feasts and other holy days. What happens to these stickers after the service? Are they peeled off and thrown in the trash? Just because these little images haven't been formally blessed or sat on an Orthodox altar for 40 days doesn't mean they're not sacred. If they weren't sacred, then why would folks be told to respectfully burn icon images on old church newsletters and other publications, and not just throw them away?
Wouldn't it be far more beneficial to inform one's flock to pray to St Phanourios for intercession in finding lost objects, and leave it at that? (I, and I'm sure many others, can vouch for the good saint's power of intercession!) I have no objection to the sale of icons for veneration, but the idea of selling icon stickers to be stuck to objects to raise money makes me cringe, to put it mildly. Surely there are better and more respectful ways of fundraising.
