Step 7Patch the holes
Working from the outside, use a couple more small plaster strips to fill in the nostril holes. Do this from underneath so the mold doesn't have to turn upside down.
Once that's set, mix up a little more alginate (a teaspoon or less, really you need very little) and patch the inside. Cover the plaster that will now be showing through the nostrils - if your alginate is not too loose, you can build this area up a little to be more nostril-y and undercut.
You can also patch any areas where you had bubbles underneath, or where the alginate tore, or was a little too thin. The new set of alginate won't stick all that well to the set alginate, so it's not suitable for very large patches. But small patches work just fine and are much less noticable on the finished casting than blobs of plaster sticking out into an air bubble.
