Masking with foam
Easy ways to masks odd shapes
January 26, 2018
For those oddly shaped openings that need to be masked, try using foam from the fabric section of your local craft store.
I find that it cuts easily with a sharp knife. You can then use a knife point or other pointed tool to stuff the foam into the opening.
The foam is easy to remove, too.
