Now that you’re tired of making HSTs let’s put them together into some useful blocks. I realise that in several places we could have used rectangles instead of squares, but I opted to go with the latter for simplicity’s sake — please don’t hold it against me 🙂

4. This is unit one. To get a better look at unit one you can click on the picture for a larger version. You need to make two copies of unit one — each copy will take 12 3″ background squares and 8 background/color one HSTs.

5. This is unit two. Again, to get a better look just click on the picture. You need to make two copies of this unit as well. Each unit will take 12 3″ background squares and 8 background/color two HSTs.
