A specific pattern for adjusting a fabric feeding amount in an electronic sewing machine with a storage for storing stitch control data for a plurality of different patterns. The specific pattern includes a 1st stitching group stored in the sewing machine and used for stitching the whole pattern in a reverse feed, a 2nd stitching group which coincide with the first one when a feed reference point is adjusted properly, and at least a 3rd stitching group which is stitched by a plurality of forward feeds and rearward feeds and is positioned in opposition to the 1st stitching group relative to a middle basic line, and gives to the 2nd stitching group accumulative errors of the forward feed and the rearward feed, so that a balance between the feeding amounts in a forward and a rearward directions of stitching is conformed.
