I've looked at tutorials on the tube method and it still appears that you'd have to have 5" fabric strips to make 4" finished size HST's.
I'll be curious to see someone explain how they turn a 3" strip into a 4" square.
When you have 2-3" strips sewn together down both sides, you cut your HST on a 45* angle. So each strip actually represents half of the HST. If these 2 strips were only sewn together along one edge and opened up with the seam down the middle, they would measure 5.5" wide, plenty of room for a 4" HST.
