Step 13 Squaring it up

Use a carpenter's square (really and "L") and see if you have a right angle on both of the wood legs. If not, you can still move the wood before the glue dries.

Don't have a carpenter's square? Find something else around your house that has a right angle. A large book will do. Or the corner of a table.
