The tri has lots of diamonds, but at least you don't have to line up the points with each other, though it is a bit tricky to make each row.
J6 is nice and straighforward, and shouldn't pose any problems.
J2, narrow strips, but PPing takes care of this.
L4, another one with narrow strips, but as above, should be OK.
These are the first set I have shown you where they are quilted. All the rest will be like that now.
As I said recently, get this week done, and you will officially be over half way with your blocks. Congratulations!
