You've described it almost exactly. Now translate it into code.
Have a list for each moving sprite.
Whenever you move the sprite, add its new location to the end of its
list and take the first value off the list.
Whenever the sprite collides with something, set its location to the
first one in the list (and re-build the list with the three items all
being that new location).
When you first create the list, make it with the three items all being
the start location of the sprite.
It's a short trail of breadcrumbs. When you find that the trail was bad
(caused a collision) you wipe it out and start a new one.
