Passing on Laura Bracken's incredible idea.

On finding the center of a circle (not always an easy task)



I drilled a hole at an intersection on my big plastic ruler (from Joanne's). I just lay my metal piece under the squares. Easy peasy.

I have a set of Swanstrom disc cutters - I love them.  I also have this old plastic centering tool my husband used to use on the end of dowels to find the center.  They both work great for finding the center of something - mostly a circle.  BUT, this is from a post on Lampwork, Etc.  Mallory wrote in about finding the center of a circle without the aid of the Swanstrom.  And what is posted above was Laura's reply.  Frankly, that would work equally great for find where to place the hole for a earring you've cut square and for lots of other applications where you need to find the center and work your way out with other holes.  This is just stinkn' brilliant so I'm passing it on.

And here is where you can find Laura's blog - which is also full of other interesting tips and goodies.
