If you have suspicions about your wife's or husband's faithfulness, then work this old Romani spell. It is said to never fail.
Take two large potatoes and scrub them clean. Cut them in half lengthwise. You will be using just one half from each potato, so you can throw away or cook the other two halves.
With a sharp-pointed knife, scratch your own name on one half. On the other half scratch your spouse's name. Place the two halves (cut) face to face so that it resembles one whole potato. Stick a new three-inch nail through the potato, with the head of the nail on your spouse's side and the point coming through your side. Then bind the whole thing around with red silk thread.
In the light of the Moon (it doesn't have to be full, but it should be waxing, i.e., moving from new to full), go out into the garden or to some piece of common land and bury the potato at least seven inches deep.
So long as the potato is undisturbed, so will
your marriage.
