Offset should result in a 1/4" seam allowance. You need to adjust them a bit. Here is one way to do this...
on each triangle, draw a pencil line on the wrong side (the side you are going to sew on)...draw it 1/4" in from the edges..all the way to the end of each side...you will have a "v" at the sharp ends where the overlap will be, and a "square" at the 90 degree end (bottom left in the lower pic). The lines forming the "Square" a the 90 degree end will tell you where your overlap should be. The lines will meet at that corner and you will have a 1/4" lip/tag sticking out. See where your 1/4" stitches are? That is where the lip/tag should start to stick out. You start your stitching at the inside of the "v" that forms.

I am including pictures of the block and the one triangle. Can you offer me advice? It is only the outer triangles that have extra material and don't lay flat. The inner triangles seem to be ok. Thank you in advance. Beth
