ColinsMum, I meant to ask, "did you just use the shorter rods to make flats and cubes in other bases?"
Sorry, I'm having trouble being clear! Friday night... There was a completely different set of equipment for each base; only the units were in common. Just as a rod looks like (say) 7 unit cubes stuck together but is actually solid, a flat looked like 7 longs stuck together but was actually solid. But you can see that in the picture, so maybe I'm still not understanding the question? Sorry!
