One of my favorite sites, ParentHacks. That's where I found Ask Moxie, actually, in a link from there.
Like most of my best finds, it was started by epeepunk sending me a link. So, thanks.
Anyway, I have a few hacks up there - the most famous being the no-sew Halloween costume hack.
The new one is more of a conversation, though. If you don't know ParentHacks.com, check them out.
