eo-2 Ladder block assembly part 2

The ladder block requires five 4-patch squares and four triangle squares. At this point, each square should be 3.5" on a side. A closer look showed that I am having the same difficulty I had with the Kaleidoscope quilt blocks - my seam allowance is coming in above 1/4". As a result, the blocks are closer to 3 3/8" on a side. I trimmed the blocks to all have this dimension.

To assembly the block, I had to take care (i.e. I had to redo a bunch of sewing multiple times!) to keep the correct orientation of the triangle blocks to the four-patch blocks. 

I sewed together 3 four-patch, triangle block pairs, and then added the remaining missing block for each row. Two of the completed blocks are shown below.

The finished block size was 9.25" on a side.
