How to deal with fabric where the pattern is not square across the width.
If you cut the fabric square when the pattern is not straight across the width (as in the example below) the panels do not line up straight at the bottom when you join.
To deal with this we cut the fabric across inline with the pattern and then manipulate the fabric to get the pattern square.
To manipulate the panel we clamp it to the table down at one corner and pull it from the other corner. This pulls the weave and the pattern up inline.
This video shows how we do it.
