I was a finger pressing failure until I was doing the dishes one day. Someone had given us a selection of wooden cooking implements. One in the set was a very tight grained, smooth, wooden spatula with no finish on it. Short. Curved. Rounded, angled tip. Just the right size and form for, TA TA, finger pressing. You too may have just the answer for finger pressing woes. It is so nice when the light comes on.
Have a good time at your workshop.
