that's a bit over engineered... you can use one finger to keep the string in place while using the other hand to draw the circle... been doing this since 6 years old...
 
У нас как-то проще делают - палец+плюс_нить+карандаш+бумага=круг...я имею в виду то, что не надо так выёживаться с нитью и ДВУМЯ зубочистками!!!!

much easier than a compass.
 
Try this with 3 and 4 pegs :)
A rectangle will produce a "super elliptic" shape.
 
this is the way Mayans made their eliptic structures, pretty nice :)
