In eliminating excess fabric from the back of a shirt, I take it that there are two methods:
i) Reducing the fabric of the back panel
ii) Darting the back (either in parallel or in curves).
However, I am just wondering if darting the back of a patterned shirt (i.e. Gingham, Plaid, Checks) will be feasible -- after all, the pattern might not line up and the back will look a bit off. Or, realistically, is it very much possible to have the pattern in the back line...
