It's funny you should ask because I sewed them into a strip the other day! I don't think I can put a photo in comments? I'm still a dw baby. But yes you're exactly right, the two go together on the long side of the honeycomb/hex shape and then you fill in the gaps with a honeycomb cross. Or you could use house shapes and a square, but not the same size of house as I made the inner cross one, as I found out when I tried (I had to have this realisation twice in the space of three days)

I'm really glad you like it!
