Yes, like that.
Although, there are 2 ways of laying out GTs. One is the way your pic shows, with 4 rows of 8 cards, plus a row of 4 cards at the bottom. The other is 4 rows of 9 cards.
Some people use one way, some use the other, some (like me) use both in different circumstances.
One other layout note: I think it's more useful to have the name of the houses written above (or below) the rectangle where the cards is laid. That way, you can still read the names of the houses when the cards are laid out.
If the name of the house is written inside the rectangle, as in your pic, it's covered by the card. To me, that defeats the whole purpose.
So I should design 2 different ones for GT. and with the names underneath or above the rectangles, not inside. Could you post a pic of the other way with 4 rows & 9 cards with the names?
