Hehe well what I am doing is importing the villager model back into Milkshape, then cut the piece I am interested (the head, 1 leg, an arm, etc).
Then in other file I create my boot attachment, and occasionally I merge the leg from the other file just to test how it will fit the real villager (then delete the merged part). Work around the villager parts, and beware that if you try to cover too much of the leg the model will clip in almost all animations cause the legs of the villager move too much.
hope that this can help you... and I will be waiting your boot and gloves Ice attachments....
