We had fixed the center door a few weeks ago and went to work on the right-hand door last night. Unfortunately, removing the old tape is challenging.
Today, we bought a can of acetone. It is *amazing* how well it does at removing the old tape and glue. And the right-hand door is now reassembled and working well.
Eventually, I will get to the left-hand door.
In the meantime, it is time to call the handyman to replace Katie's bedroom door, which is now falling off of its frame.
