If you only want to make it wider.. when you cut your strip sets and an extra 1/4 inch to each strip set cut. If you add just extra to just the first strips( prior to sewing the strip sets) it will be longer but not wider.
I did this on a bargello and it had no effect on the final design appearance. I did go through and added a strip of paper across the top of the strip set cutting guide and put the new measurements. I figured at some point it was likely I would forget to add the extra.
