I made block 8 yesterday! The tutorial can be found here. Although, just a word of warning, the tutorial is not complete. I was extremely confused for a while. Essentially the tutorial skips the last few steps, where you add on the red part to the two halves to get a symmetrical square block. The unfinished size is supposed to be 11.5 x 11.5.
My colors are a bit different from the original as you can see. The reason being is I didn't want my background color to be off-white, so I picked a light green. I think it goes with the other 2 quite nicely. I also like my fussy cut birds if I may say so myself.
