Brat, only ONE block is required. If some want to do 2 blocks or side swaps that's between each other. Hope that ans'd your question...;o)
GOOD GRIEF - just had an earthquake hit here! It was strong enuff that it shook things in here, my desktop shook!! My Boxer about fell over...Man, that is a weird feeling!! There's been quite a few hit here in the last few days - they don't know for sure what's causing them.. Whew, I'm still shaking!!! They just mentioned it on the news, the size hasn't been said yet.. I cannot imagine going thru a big one like they have in Ca..!
OK, have a good nite..
