Got last years furs back and wanted to reshape them just to look better. I’m assuming I can soak them in water and put them back on a stretcher fur side out and just let them dry?

Might try a spray bottle on the flesh side only. Then tack out however you like.

Are you looking to shape them like they are on a stretcher? if so, wet the skin side down and put them back on the board, pull it down and secure it. Let it dry that way. If they have tails. Wet the skin, open the tail and secure them with a long needles or pins to keep them open. I think Boco had pics on how he does his fox and coyote tails. Maybe someone can put it back up.

You don't need to soak them. As mentioned above, use a spray bottle to get the leather moist. You can easily pull the hide this way and that to re-gain some size and will help with pliability. If the skin is cased, you can put the pelt on a stretcher and tack the base and tail to the shape you want, and don't forget a wedge! After tanning, the pelt might not fit the original sized stretcher you used when the pelt was green, so a size smaller may be required, as tanning can reduce pelt size by as much as 20%, (though re-hydrating the leather will allow you to regain some of that).
If the pelt is skinned "open", after doing the above, simply re-tack it to the desired shape and let dry.
