|Yes, generally speaking, circle kits from all manufacturers provide just enough of the smaller pieces or wedge-shapes to get you to a complete outer 'ring' that can be formed using full blocks (usually the smallest of those available in the product range) laid with 'gaping' joints that, in theory (and to comply with BS7533:3) should not be wider than 5mm.|
From there, you just add as many additional rings as you wish until you reach your desired diameter.
One word of advice with large circles: the trueness of the circle arcs tend to reduce as the circle grows, and on large circles, 10m radius or more, the effect at the outrermost edge can become noticeable, with 'flat spots' on the circumference followed by fast arcs, all of which adds up to a rather freehand look to the circle, even though the inner rings are geomtricly accurate. So, use a tape measure from the origin to ensure that each additional ring, as it is being laid, is being laid accurately.
I think your comment about using the small blocks once you go beyond the supplied circle is maybe why it looked a bit odd?
Good tip on the measuring as you go.
