A caution about enlarging patterns on a copier.
I have been told that all copiers are not equal in the accuracy of enlarging designs. This is deliberate on the part of the copier due to perhaps copyright issues. This, of course doesn't apply to a design such as the Drunkards Path.
It is a good idea to check the accuracy of the enlargement before using as a template for cutting.
The DP is a rather simple design to draw with graft paper and a compass. So when you get the enlargement made, without the seam allowance, check it with the compass to make sure the curves remain true. I would draw two patterns and then add the seam allowance for each section and then make a template of each side (which you will probably do anyway. I cut each section and then glue to stiff plastic and then cut out. The curve muse remain true for each piece to fit accurately.
