Step 9 — As your rows of studs begin to meet on the back of the collar, be careful to check your spacing. Here, you may find it helpful to place the remaining rows of studs at once, and then flip the collar over and secure them all at the same time. That way, you can make the final adjustments in your spacing and easily move the final studs, to prevent ending up with a row of studs that looks cramped (or getting a gap that looks like it should have another column).
