The litter bin tells all and spills the beans about what I have been doing. Each Log Cabin block had to be trimmed to 9 ¼” and I couldn’t do this accurately without a large square ruler; they are brilliant for the job. Once I had squared up one corner, I rotated the block and lined up the ruler with the appropriate marked line. All I needed to do then was to trim the remaining edges. There should be no joining of blocks until they are all the same size.
