An eight of an inch!

Who knew, an eight of an inch could make the difference to a diamond to fit inside all those triangle squares.  When the strips were cut originally, the measurement was not one I was familiar with, so I cut the strips just a fraction wider.  Lesson number one, stick to the exact measurement.

The four corner pieces which will create the square in a square.

All the triangle squares were trimmed before sewing them together. This is crucial to keeping everything on track.

At this point, everything was fine.  I forgot to trim the green strips of fabric by an eight of an inch all round. This caused a number of headaches, preventing these larger triangles from fitting around the center square.

It had bubbles and was not lying flat.  So out came the unpicker and the book, the ruler and then it was a case of going back to the green border and trimming it by that eight of an inch on each side.

The end result, a square in a square which lies flat.

Miters can cause problems, in this case it was getting the measurement right. Nothing more frustrating than trying to quilt a quilt with a bubble in it, down the line. Moral of this story, do it right first time round.
