Here's the ruler with 2 blocks. You don't need the June Tailor ruler for this, as someone else said. The idea is to use the tape to lock in the block on the diagonal. It makes the whole process faster and more accurate for me. I place the block under the left diagonal line, lock it in place with the tape, and I trim the 2 vertical edges. Then I rotate the block 90 deg, place it under the right diagonal line, lock it in place with the tape, and trim the other 2 sides that are now vertical.
Any ruler with 45 deg markings will do, but I do love the June Tailor ruler for this.
Hope that clears it up for you.
