Sometimes, you may notice cracks appearing on your air-dry clay craft during the drying process. This is completely normal, as air-dry clay tends to shrink slightly while drying, causing cracks to form.

But don’t worry! Fixing this is simple and easy. Grab a small amount of extra clay—just enough to fill the crack. Then, wipe a little water onto the spot and use a tool or your fingertip to smooth out the surface. Try to make it as seamless as possible, and you’ll have the smooth surface you want!
