I've been putting a garden shed together, which I've never done before. It came flat packed, and the instructions are not as good as I'd hoped. It says to drill holes here and there and all over the place, and it's not always clear to me where or what way around parts are.
I am slowly and carefully doing it because you can't un-drill a hole! I don't exactly want holes all over my shed! I've already worked one one of the walls I had back to front, so lucky I didn't drill that one until later.
