Lay the item to be repaired into the hand press so that the hole from the original snap rests directly above the shaft of the post.

If the fabric around the old snap is torn or damaged beyond a small hole, apply a patch to reinforce the area before replacing the snap.

Make sure no extra fabric is caught inside the press and that the orientation of the item is correct.

Hold the fabric in place with one hand, then use your other hand to pull down the handle of the press.

This requires a lot of pressure to make sure the snap replacement is successful - so pull hard!
