Someone was asking earlier about the original A1 block in the Dear Jane quilt.
OK , I drafted the orig A1 at 4.5" block in EQ5 and wanted to find an easier way to construct it.
First, I worked on the center square on point. Sew 2 - 2"x12.5" strips together and press open. I don't have a 45 degree triangle ruler. So I used my 45 degree angle on my straight ruler. Mind you, this does not have the tip cut off like some triangle rulers, so the tip is included in the strip measurements. I cut 8 triangles alternating turning upside down. I sewed them together to make this
I then used my block printout and cut out the center square on point. I trimmed this back to that size making sure to add the seam allowances. So the overall trim size comes to 3 7/8" square. My block came out just a hair small, so you might want this trim to be 4" square.
This is now my final block, which is a tad small. When I redo it, I will make the corner squares 1.75" and the tiny triangle 1.25" instead of the 1 3/8 in this block... it seems a tad large on this block. The setting triangles should be cut from 2.25" squares cut corner to corner.
