Well, you are back now with four blocks and a tri, after the 'easier' summer weeks, so I hope the extra one doesn't seem to many to make.
The Tri is straightforward, I think. No terrors there as far as I can see.
M9 is supposed to be mirrored, and I don't think I did it that way because I always managed to forget when printing out. Lots of little pieces, but step by step and you will get there. I prefer the way the border on this one goes, more the way we do borders on quilts nowadays, rather than what seems to be Jane's preferred way, (as in M11)
D 12 I did this by making the four main squares first in three pieces, patterned, plain and patterned, then I appliqued the little patterned square on the outer corner of each. In other words, I chickened out on doing four internal corners. Call it sneaky, but it was just quicker for me.
E 1 As long as you now have melons shapes sorted, then this one will be a doddle, as they are nice, big, easy ones.
E 6 Fiddly looking middle part, but paper piecing works well for this. Do that section in quarters, two halves, then sew them together. With the isolated squared on the outer four tris, you can either opt to applique them, or extend some lines outwards from their corners, and then seam them in. If you opt to extend the lines, you can either go out towards the corners, or make them parallel to the long side of the outer tri. Hope that makes sense.
