Designing with French Curves Introduction.
You can, using various sized Compasses, create some very nice symmetrical designs for burning.
Designs can be worked out on paper, then re-graphed to the wood still using the same tools as used on the paper design. I gave an example of this on a page on this site.
However for smaller designs on say a tea coaster, it is sometimes difficult to do this, as the needle point of the compass often has to be off the wood and the pencil end on it. This is where I developed using French Curves.
They are useful for small and large designs like these below.

For those not familiar with French curves, I have posted a picture below of the ones I have used for some years now, though they come in all sorts of sizes and materials.
