Day 1: I finished sewing the blocks, sashed it all, sewed the blocks together, and added the border.
I will apologize for this being a little shorter, but the main detail was in the prior post for making this quilt top. You can see the prior instruction post here
To put the top together I made vertical strips: 2 strips were 5: 3x3 blocks and 2 strips were 1: 3x2 then 1: 3x3 block repeated twice. Each of the blocks had 2 1/2" strips of sashing between them. When the strips were made, the strips with only 3x3 blocks is 2" shorter than the other strips. Because of this, I added a strip of sashing to the bottom of those two strips.
Next, put sashing on the sides of the long strips you just made and sew them together.
Last, add 5 1/2" border around the outside edge.
