Wow, I love the second one too! It doesn't look hard to just figure it out. It looks like 10 blocks wide x 12 blocks long plus borders. Looks like a queen size bed which is 60"x80" and there are a little less than 8 blocks across the top (not including the drop) so I would say that the blocks are 8"x8"? The red border looks like it's twice the width of a log cabin strip so about 4", then the last border is pretty large, maybe 8".
I would love to see a pattern for it too.
