Things I discovered along the way:
Straight boards may not be truly straight, even if you do all the right checking for straightness!
It is very difficult to hold two long boards at right angles by yourself while you screw them together! (Maybe this was the real problem!) My daughter helped me hold the boards and watched to make sure the screws didn't pop through the wood at the wrong angle. She was so proud of helping me build it! I took pictures of her but now can't find them on my card. Sigh.
The next projects on my list are Anna's toddler picnic table, the activity table and bunk beds! My husband will have to help me with those I think! Check out her site and get inspired and start building whatever you need (want) in your house!
