One DIY site that I always forget is Instructables.  I have found some interesting stuff there.  I haven’t posted any of my own istructables, but I hope so soon.  In the meantime, I encourage you to take a look at Instructables and its many offerings.  You can find instructions on anything:  from food to relationships, to sewing to technical gadgets.  It’s fun!  Learn something new and perhaps contribute something yourself.
In the meantime, here are some of my favorite Instructables.  Go and learn something new!
